T Mobile Global data coverage
 

I was in Mexico/Guatamala for 3 months earlier this year(Jan 2- apr4 all roaming exc wifi) and did not have an issue w/tmobile. I did not use a lot of data (low volume email,maps,apps) but a fair amount of time 20c/min on the phone.

Is it also 20 cpm to call back to the US?

Yes.

Quick side note. Free Tmobile router arrived and it is fast. Call and get one for free!!

Just spent two weeks in Italy and TMO was pretty good. Only complaint I had was in the last two days I was there, my phone (new Note 4) seemed to have a hard time getting a data connection. Odd that it was fine for the first 10 days (no problems at all) but for some reason very balky at the end. I was in different places so that may be part of the problem. OTOH, my wife's Nexus 7 kept its data connection up more reliably.

Last winter, when I was in Sicily, had no problems at all provided there was cell coverage.

Did you force LTE off if your device supports it (e.g. LTE not on or set to 3G or WCDMA only). bad attempts at LTE connection can drop you from the network. I was noticing this on SKT in Korea last week

This thread is very interesting and I guess thanks for posting it up.

I've been wondering if I should switch to T-Mobile to save on the roaming data, but it seems it's not working that well everywhere. I know for LTE roaming your home carrier needs to sign new agreements with the roaming carrier, so I assume T-Mobile USA hasn't done this? This would explain why it works on T-Mobile DE only since it's technically the parent company there is no agreements needed.

I ask this because I currently have AT&T and when I roam it connects to any available network (including LTE) on just about every place I've been to. It even works on cruise ships and you know how restrictive [and expensive] those are. The only issue I have to roaming voice is very expensive, so I forward all my calls to my Skype account which I can answer with via data.

So I've been debating switching over for a while now. I'm current paying $65/month for the data plan, but my roaming voice is like $2/minute.

Definitely had this problem in Tokyo and Hong Kong though not Taipei. Unfortunately didn't learn about turning off LTE until halfway through my trip.

Overall happy with this service from TMO. No regrets about switching from AT&T. A little slow but good enough for maps and email.

The free roaming data on T-Mobile is 2G. If you want faster data you have to pay for it, although there have been a reports of people getting faster than 2G speeds now and then. Calling is .20/minute.

Overall, imho, it seems that posters on this thread are quite pleased with how the program is working.

I've seen my question(s) asked in various places, but never a definitive answer, so I'm calling on the collective experience of posters here: what calls made while roaming are not possible and/or get charged at higher rates?

I'm assuming that calls to 'premium' numbers are either blocked or ridiculously expensive, which is fine, but what about numbers that are intended to be free for callers (1-800, 0800 etc.) -- do they also go through for 20 cents per minute?

Also, does it make any difference whether the number I'm calling is a landline or a mobile/cell/wireless account? If I'm calling the US it obviously won't, as cell numbers use geographic area codes, but that's not the case in many other countries.

I just want to be more confident about what to expect before I start calling German mobile numbers when I'm roaming in Sri Lanka next month... @:-) Thanks in advance for any information (which we can add to the wiki as appropriate).

From what I've seen on my bill so far I'M NOT being charged anything other than the USD 20 cents

Example of detail on this months bill while roaming in the UK and Germany (I masked the destination numbers). Date/Time, Dest #, Call charge type description, (R) = Roaming, # of mins, cost

Further down my bill I have a better example of calling countries other than US while roaming:

11/04/14, 8:32 AM (416) 5xxxx South Korea (SK Telecom) to Canada (R) 6 $1.20
11/04/14, 9:42 AM (408) 7xxxx South Korea (SK Telecom) to USA (R) 7 $1.40
11/04/14, 6:28 PM 49172xxxx South Korea (SK Telecom) to Germany (R) 4 $0.80
11/04/14, 6:32 PM 336xxxx South Korea (SK Telecom) to France (R) 7 $1.40
11/04/14, 6:45 PM 8180xxxx South Korea (SK Telecom) to Japan (R) 1 $0.20

Nothing other than 20 cents a min charged and no post billing from last 3 months for any surcharges.

Notice on the first batch, ONE 800 number (877) it was charged at 20 cents a min like other calls. You will notice there are mixed in mobile numbers in Germany and France and none got dinged a higher rate.

So safe to say T-Mobile US is eating the cost and doing a flat rate 20 cents a min fairly.


I have an AT&T MiFi for work which I use as a worst case backup; I've not had a reason to use it other than once in the last month. This WAS NOT working for LTE networks for me in some countries; so YMMV. You can assume T-Mobile US will execute more LTE agrements; but it's essentially moot if 3G is throttled for roaming LTE will get you better network latency but not a huge reason to pay a lot more with AT&T and may ripoff rates for Voice.

That's extremely useful, NickP 1K, especially given that Germany and the UK are my most frequent non-US locations. Many thanks. ^

Anyone successfully used T-mobile data plan for VoIP in Germany recently?

The VoIP worked for me great in Jan this year in Germany, Switzerland and France (although it is 2G speed, it is enough...reasonable voice quality). But I was in Canada in July and VoIP didnt work (it was not the speed, rather it was getting blocked).

TIA

Thanks - no I didn't (and didn't know it could be an issue). If I run into the same problem week after next in Munich, I'll give it a try. This also explains why my wife's Nexus 7 3G seemed to stay connected more reliably.

I was using it in UK/Czech Republic/Germany/Italy/Netherlands in June/July , no VOIP issues.
