This is a user-maintained wiki FlyerTalkers with at least 90 posts and 90 days of membership may modify and update this information.
Please edit available network carriers or LTE networks if you find the information below is out of date.

Effective August 1st, 2018 :OPTIONAL high speed data roaming for international (non Canada/Mexico) has changed to be $5 USD per day for up to 512MB of high speed data per day. This also includes unlimited inbound and outbound calls avoiding the 25c a min call charge. You can add this via 611 or this link: https://my.t-mobile.com/odf/DataPass:ALL - It is labeled as "24 Hour Global Pass". If that link doesn't works go to "Manage Data & Add Ons" in plan settings at http://my.t-mobile.com . A pass covers ANY countries in the given validity period - NOT just one country. So if you travel within multiple countries in the 24 hour period you get a max of 512MB of high speed data and unlimited calling across ALL countries prior to pass expiration. This is OPTIONAL and is not required, free 128Kb/sec or 256Kb/sec speeds are provided for users who don't pay for this extra data pack.

Effective July 15th, 2018: Calling rates for inbound and outbound calls were raised to 25c a min from the prior 20c a min when roaming internationally. You can buy a per Intl High Speed day pass for 512MB of high speed data that also includes calling at no cost during the validity of the pass.


Effective Feb 17, 2017: T-Mobile has bumped up speeds to 256Kb/sec for T-Mobile One users - this was FREE for a promotional period and required you to edit the lines with this plan to add the free or higher tier paid "T-Mobile One Plus" line item. The free line item is "T-Mobile One Plus promo" which will allow that line to be 256kb/sec and will also give 10GB of LTE North America hotspot tethering - The change can be done at my.t-mobile.com under plan for T-Mobile One customers or through 611. With the promotional period ended you can add the base $5 T-Mobile One Plus item to get 256Kb/sec

SUMMARY: T-Mobile USA on Simple Choice or newer plans (such as Select Choice) or T-Mobile One that list "Free International Roaming included" allow for free data and SMS in 210+ countries. Data and SMS is FREE; voice calls; inbound or outbound to any of the 210+ countries while roaming are 25 cents a min. Free data is NOT offered on T-Mobile essentials users outside of Canada/Mexico while SMS and 25c a min calls are still offered.

Canada and Mexico include FREE high speed roaming (HSPA or LTE full speed) as long as you are on the Simple Choice North America plan or a T-Mobile One plan. A monthly cap of 5GB for International High speed data in Canada and Mexico is now present - data will slow to lower speeds with no overage charges. Users on T-Mobile One Plus International are exempt from this 5GB cap.

You must be on a Postpaid plan, Prepay is NOT eligible nor is MetroPCS

NOTE: Devices with fully FREE data (e.g. 200MB free for tablets) and not on an additional plan are NOT eligible - switch those devices to a supported plan PRIOR to travel or you will be charged per MB fees.

WARNING: Highly suggest going to: https://my.t-mobile.com/profile.html (or login to my.t-mobile.com select profile), go to blocking and ensure "Block charge international roaming" is set to ON - keep "Ensure Block International Roaming" is set to OFF otherwise roaming will not work even in free data countries. This will ensure in countries where you are close to another country border that may NOT be part of free data roaming you will never be charged for data by ending up roaming on the adjacent country network if your phone is set to Automatic on networks.

WARNING FOR HIGH SPEED ADD ON $5 DATA PASS: Ensure you know your end date/time and heed the SMS warnings sent. You will be liable for 25c a min per call inbound or outbound if the pass expires and you do not activate another pass. Ensure you purchase another daily pass before making phone calls. As of Early August 2018, there was no method to purchase multiple days in a row.


T-Mobile FAQ:
http://support.t-mobile.com/docs/DOC-9455

Checklist for Roaming - follow this prior to leaving!:
http://support.t-mobile.com/docs/DOC-2182

Performance:
Speeds are throttled to 128Kb/sec on all supported plans, except for T-Mobile One Plus Add on (includes the Promo Feb 2017 T-Mobile One update with free One Plus Promo) which is 256Kb/sec. Connecting to the best network type possible will ensure you hitting these speeds limits (e.g. LTE). Performance is subject to the roaming carrier networks condition (is it congested or not) and how good the back-haul from the roaming carrier back to T-Mobile is. Reminder that T-Mobile Essentials users will have NO access to free data.

Filtering:
Your connection is terminated back to the US, so anything that works on T-Mobile US will continue to work. Example: China filters social media and Google services, using these services through your T-Mobile line won't experience this networking filtering. Local services in the country you are in MAY identify you as being in the US - any services that do IP geolocation will see that you are in the US.

Optional High Speed On Demand Data Passes with unlimited calling
If you want performance that is beyond the 128Kb/sec (or 256Kb/sec on T-Mobile One Plus Add ons) then a PAID optional high speed data pass removes the throttling performance limit. Effective Aug 2018 this pass is a $5 PER day for 512MB of high speed data (per day) and unlimited calling to allowed countries, waiving the 25c per min charge for inbound or outbound calls. To add, go to: https://my.t-mobile.com/odf/DataPass:ALL and add the "24 Hour Global Pass". If that link doesn't work add at http://my-t-mobile.com under Plan, "Manage Data & Add Ons" More information: http://support.t-mobile.com/docs/DOC-7261 NOTE: As of Early August 2018 you can only purchase one day at a time, so be cautious on expiration (Notified via SMS) to add another day pass to avoid getting charged 25c per phone call. A pass covers ANY countries in the given validity period - NOT just one country. So if you travel within multiple countries in the 24 hour period you get a max of 512MB of high speed data and unlimited calling across ALL countries prior to pass expiration.

Country List at time of July 2018 update:

NOTE: there is no T-Mobile provided list of specific network roaming partners; you can call 611 and ask for a roaming specialist/tech and they can tell you per country roaming partners - we are attempting to capture working or problematic networks in this Wiki below also

Need Support while traveling? Read the hints below FIRST; then if support is needed call direct intl support for T-Mobile USA: +1-505-998-3793 [FREE CALL WHILE ROAMING] or if you cannot get Voice access use Skype or another service to dial.


Hints

#1 HINT: You MUST have Data roaming turned on - You will only see foreign networks on the network list - you will NOT see T-Mobile. Manually pick the networks from the list further below if you don't automatically connect.

- You do NOT have to pay for a high speed data package. 128Kb/sec (or 256Kb/sec on T-Mobile One Plus Add on) FREE throttled data is inclusive on all eligible postpaid plans

- High speed un-throttled data is also FREE for Canada and Mexico if you are on a Simple Choice North America plan or a T-Mobile One plan for up to 5GB of data per month (T-Mobile One Plus Intl users are not subject to the 5GB cap) . If you are not on these specific plans but on a legacy Simple Choice plan you will get standard 128Kb/sec FREE.

- For paid high speed packages, You can schedule WHEN optional high speed paid packages start (immediate or a time/date you set).

- On some accounts, High speed on demand data passes will will not be listed on my.t-mobile.com - under plans, "Manage Data & Add Ons". You can also contact customer care at 611 to add a data pass.

- If you purchase a package on phone or hotspot and are about to expire you can purchase ANOTHER one if you want and even though it will say "starts when your existing package date ends" it will IMMEDIATE activate it when you run out of data. Example You pay for 200Mb for one week and will eat into 200Mb, you can buy a package ANYTIME and it will future date it as being effective ONLY when the existing package date ends. HOWEVER once the existing package data amount is used up it will IMMEDIATE activate the paid pending package.

- On Demand Mifi WILL not roam at ALL if no package has ever been provisioned. Use the free data on your smartphone (or use another device with WiFi) and log into http://my.t-mobile.com Once logged in go to https://my-tmobile.com/Plan/Plans.as...vid=changeplan View plan for hotspot and and change plan, under Data Tab when viewing change plan add a package; once you confirm and submit (ENSURE before you submit you are adding to correct line!) you will get a confirmation. It was about 5 mins and then hotspot was able to connect to network.

- On demand Mifi WILL STOP working at end of time period NOT at end of data usage. So if you pick 500MB package which is 2 weeks expiration, it will actually STOP full speed at 500MB and revert to a 64Kb/sec speed till expiration; this ONLY applies to packages purchased on on demand hotspots. If you purchase a package for a smartphone you will revert to standard 128kb/sec

- Hotspots with On Demand will lose network access at end of paid period even if it reverted to lower hotspot only speed of 64kb/sec. So top up before you lose network.

- Legacy data match for tablets or hotspots (no longer offered but still allowed for current users) support 128Kb/sec on tablets and hotspots. If your data match plan details show match with North America added in the description then you get high speed in Canada and Mexico that uses your data match limit (up to 5GB) - after than you revert to 128Kb/sec. T-Mobile One Tablet will provide 128Kb/sec by default, if a T-Mobile One Plus add on is on that Tablet line (Including the free Feb 2017 One Plus Promo) speeds will be 256Kb/sec

- You can check current usage on any paid packages my viewing on the T-Mobile Application for Android or iOS or going to My T-Mobile website and filtering data usage on the line for International Data Roaming.

- When using a T-Mobile supported international data roaming plan on an iOS device internationally (in a nation on the 'free' list), you need to turn on Data Roaming on the iPhone/iPad Settings.

Troubleshooting

- If finding no networks when in new country, go to Airplane Mode - then back off Airplane mode and try again. If this fails to work FULLY power off phone and power back on. You may need to do a manual scan of networks on your device and pick one of the KNOWN networks below in the country list.

- If still not connecting to a network do ONE more phone reboot and attempt again.

- If you do connect to a network but are failing to get data, dial in your phone dialer #RON# (or try #ROF# FIRST then try #RON#). #RON# will turn intl roaming data on, #ROF# will turn it off. Sometimes cycling will cause a network to work.

- If connected to a network for Voice/SMS but still not getting data, set phone to Airplane mode ; wait till device is actually in airplane mode (15 sec or so); then take device off Airplane mode.

- If failing to get GSM/Voice/SMS services but you have data and phone shows "Emergency Calls Only" but data is working suggestion is to switch phone to 2G and connect to a network where you get data and voice/SMS. Once connected to that network switch phone back to 3G/Auto or LTE (or similar setting) and this may correct the issue. (Your mileage may vary)

- Try to change your APN to fast.t-mobile.com per the following guide, as an alternate you can try a temporary switch to epc.t-mobile.com - more details for APN change further below

- If none of these work, dial TMO Intl support +1-505-998-3793 (from another phone or Skype) and ask for "International Roaming Support" (make sure that is who they connect you to by asking the agent if they can help on a roaming support issue) - have them check your account is properly setup and eligible for International Roaming.

Note: These settings are automatically set to the correct values with the Carrier Update when a T-Mobile SIM is inserted.
  1. From the main menu, tap Settings
  2. Tap Cellular.

I'm thinking of switching from AT&T to T-Mobile. I get bad reception at home for both, though they're about the same in most of the places I frequent.

I guess if I traveled more in the US, especially outside of major metro areas, I could regret switching.
WiFi calling is decent. I've noticed the quality is more or less the same as the mobile network as long as you have a low latency Internet connection. T-Mobile will give you a signal booster if you have marginal reception inside your home.

Thumbs up Japan, Singapore, and Thailand Part 2

Just back from my 2 week vacation. Here's an update since my original post.

Thailand
-After a couple days in Patong the display changed to TH GSM and I had Edge data the rest of my trip. I didn't try to go into settings and force it back on to DTAC. I had slow data service the entire 2 weeks of my stay, and got many SMS messages.

At some point during my trip I applied the 5.0.1 update to Android Lollipop.

Singapore
-On my return trip while spending a few hours at Changi airport, my phone automatically selected and connected to M1. Display was SGP-M1. HSPA+ service.

Japan
-During a layover in Narita airport my phone first automatically selected and connected to NTT Docomo UMTS service but soon switched to Softbank. HSPA service in most areas with some spots where it falls back to UMTS.

It just happened that no one tried calling me during this time, and I made no outgoing voice calls. That's not unusual for me, I use SMS and data almost exclusively. I used WiFi in my hotel, restaurants, and in airport lounges whenever possible. Still I had about 500 MB of cell data usage while internationally roaming in the current billing cycle.

My phone is a Nexus 5 US model running Lollipop 5.0.1 I continue to be very happy with my T-Mobile service.

Question about WiFi calls overseas. Reading the past few pages it seems you get charged calling over wifi, is this correct? If you use Skype when connected to a hotel's wifi to call a non-us number you still pay per minute? I assume this also applied when calling using data when roaming? Are there any voip apps that get around these charges? Not sure how t-mobile knows that certain data is a phone call? Especially when you're connected to wifi.

If you use Skype to call any number you will pay per minute (through Skype, not T-Mobile). If you call overseas using WiFi to a US number there is no additional charge. The problem was coming in when using WiFi to call a third country (Canada) while overseas (the Maldives) the person was billed the cellular roaming rate ($5.99/minute) when he should have been charged as if he had placed the call over the US cellular network since this is how T-Mobile sees the call.

As Lebanon is not part of the plan coverage, just wanted to share the information received once I arrived into Beirut..

Welcome to Lebanon. Out of plan coverage. $.0.50/text and $3.59/min talk.

Caution: Charges for web, email & apps while roaming are $15/mb + tax

Expensive as everything in Beirut...

It will be nice if someone could list them on the wiki

I.e. Skype / Facetime (for mac users) / Viber / Line / Any other app where you can actually call your contacts for free while roaming or over WIFI.

Any of these won't generate charges from T-Mobile when directed over WiFi because T-Mobile doesn't see any of the data. When going over the local mobile network it's governed by if you get unlimited 2G web/data speeds in that country or if it's billed at a metered rate. If the connection is good enough to maintain a Skype/Facetime call, you'll be fine.

The issue comes in with WiFi calling (over T-Mobile's network) to other phone numbers. I have an international discounted calling plan, so I will check out a few corner cases next month.

Got it, so I can use skype and pay their rates when I'm connected to wifi or roaming internationally. Is the "free" international roaming fast enough to place voip calls through skype/google voice normally? If so I'm not sure what the benefit is to use t-mobile's wifi calling or $0.20/min calling? In my experience the cost of skype calls is a fraction of $0.20/min. Haven't really had quality problems with skype if the internet connection is decent.

I got this text from T-Mo today, "Effective January 13, 2015, we are no longer able to offer data roaming in Vietnam (this does not impact voice calls or text messaging). For more details: http://m.t-mo.co/buVvo"

Bummer!

T-Mobile Comes Through! (a bit of Vz bashing...)

The president of our company was traveling to Costa Rica for the holidays, but needed to keep in touch. Our corporate plan is with Verizon, so I went ahead and swapped out his hotspot for an international version and added the data plan (100MB/$25), so that he could keep in touch on his computer. I gave him the 4th line of my "4/$100 plan", which he placed in his old iPhone 5, so that he had 20-cent/minute calls (vs. $2.89/minute on V...). With him in Costa Rica not less than a day, his hotspot stopped working - he texted and I was on the phone with Verizon. Come to find out, they have no roaming partner in Costa Rica, so data is $20/MB - meaning when he hit 50 MB, it triggered the $1000 lockout on the line... I was pissed (as was he). At least his T-Mobile phone was working for data...

Quickly went online to my TMo account and added a 200MB higher-speed plan to my line (for the same $25). I sent him the instructions for turning on "Hotspot Mode" on the iPhone 5, and got the "Worked. Gracias." text message. Whew!

My wife used Skype to place a call via the international roaming, and it sustained a conversation for 30 minutes. The benefit of the $0.20/minute calling is if you're not near a WiFi HotSpot and need to get in touch with someone you aren't gouged with a $1-5/minute rate to make a quick phone call. T-Mobile's WiFi calling is free back stateside, but they've changed the billing such that you will have problems if calling anywhere outside of the US in a non-$0.20/minute location. (In these cases, it makes sense to use Skype anyway because the per minute rate is cheaper.)

I just got the iPhone 6 from T-Mobile (2 weeks ago) and went to Mazatlan for the past week. While the texting and phone service was excellent (connected to Movistar) I noticed that even though the phone would indicate 3G speed, there was no data connectivity. I have read that this could be due to the fact that the iPhone 6 does not have support for the signal band that Movistar uses. Has anyone else encountered this, and if so, was there an option on the phone that needed to be changed in order to get it to work?

Most phones should support all 3G bands.

iPhone is suppose to support the most number of LTE bands. The one you buy in the US could be used in Asia and Europe whereas other smart phones have different SKUs for US vs. rest of the world.

Latin America may be further behind. For instance, I was researching going to Argentina, which doesn't have any LTE networks yet.

In the phone, was the option to allow for data roaming, enabled?

But, wouldn't the phone pick up the 3G signal and utilize that, albeit that it would be a much slower connection?

Yes, I even made a point of it to turn it on--when I landed, it acquired the Movistar signal, but for whatever reason not the data part of it. I also reset the network settings too to make sure that there was nothing else in the settings that would prevent it from working.

PS-whatever you do, don't disable iMessage as it is a gargantuan pain to re-enable.
