Quick question regarding settings in android phone (using Nexus 4) Do I have to check button "enable data roaming"? Do I have to select network? Thanks for help.

On iOS you have to enable data roaming.

On iOS, you can select Automatic carrier selection or select them manually.

Data roaming should be enabled. As to your second question, my friends Note 3 automatically selects a network when we are travelling while I have to manually select a network on my Moto G.

If you take the trouble to read the preceding sentence in his/her statement all will be clear.

I have a Nexus 4 and just got back from a month in Asia (China, Thailand, Japan) and it worked great without selecting network. Data roaming was enabled.

Plenty of speed to use Google Maps, email and most apps.

I did take the trouble. It said:

He makes a blanket statement which simply isn't true. While there are a few countries that are problematic, the reports on this thread from many are consistent with my personal experience: it works as advertised in most cases.

LMAO...thanks for that ! :)

I'm preparing for my RTW trip and I'm looking for a global data solution. Has anyone tried the bxdigital $15 for 6 months sim? It's a T-Mobile simple choice sim thus it has free unlimited international data roaming. It's only 2G while roaming but for my purposes, that's fine. $15 for 6 months is more than I need but cheaper than any other option I've found. There have been reported problems. Bad sims being sent out and plans being canceled. Yet there are some good reports. Has anyone used one internationally? I'm especially concerned about speculation that it's a tablet only sim. I want to use it with my smartphone. I don't want it to work for 2 weeks and then die while I'm on the road.

Here's a howardforums thread about it.

I have Tmobile and it is sketchy.

In Peru, it offered 4g services(no LTE)and used it alot. infact I uploaded over 100pics to FB on the International Data. No additional charge

But In the Phillipines, it didnt work. Free SMS texting worked, but NOT Roaming Data
In Thailand, it didnt work, Free text, but no data
In Singapore, it did work 4g, no LTE
In Japan, it didnt work
In the Dominican Republic, it didnt work, only text

I think on certain networks, you need to add or change the APN. But unfortunately, I do not know how.

I just picked up a Tmobile sim and used it in Germany, Italy, Spain, France and Switzerland. It "worked" seamlessly enough, but was very slow at all times. Slower than 3G, for sure. It seemed like I always had only one or two bars, even in large cities. I let it choose networks automatically.

There should not be a need to change APN. You are not changing sim cards. So, your device already has the tmobile APN. It's possible that they may not have data roaming agreement in those countries.

I am in Japan at the moment and it is working perfectly over Docomo Network.. depending on the area (Yokohama & Tokyo) sometimes jumps between Docomo and Softbank but most of the time is working for me...

in which area of Japan you were traveling?
