I have an unlocked T-mobile Galaxy Tab running the factory ROM. I want to use my iwireless unlimited data sim in the tab. When I put the sim in and change the apn to i2.iwireless.com I can only connect via edge. With my T-mobile sim I get 3g. Iwireless is a T-mobile affiliate and should get 3G. If I put the iwireless sim in a laptop stick I get 3g. Anyone know what I am doing wrong? Thanks in advance!

Hi, all,
I have a quick question:
I was in Smith, Nevada recently, using a G1 with a Tmobile SIM card, and the phone did not get service. However, the phone did say that there was an ATT network present, and my friend's phone got reception just fine. However, when I tried to manually switch to the ATT network on my phone, I got a message saying that the sim card does not allow me to register on the network. How can I make the phone register on the ATT network when there is no Tmobile service?
Thanks,
Tekgek
Allow roaming? Best answer I got.
You could buy a cheap pay as you go att phone and swap the sim in yours.
Errrm, I think roaming is enabled. Is there a hack or something that can override the sim card's programming?

I've read through the threads I could find, but haven't been able to figure out if I could get 3G speeds using an ATT data sim in a T-Mobile galaxy tab. Does anyone know? And if it's possible, how?
I don't think you can. T-Mobile and AT&T use different radios for 3G.
Never gonna happen, different radios. Edge speeds will work but 3G won't.
I picked up a used Samsung Galaxy S i9000 that was on Virgin (CDMA?). I rooted it, and put JB on it. From another device, I have a Telus data plan that is on 4G. Looking at the i9000 specs, it says it supports GSM and 3G. This where I get confused. The Telus plan I am on is 4G LTE (data). Does this mean that this Sim could fall back to 3G if I use it in my Samsung? I have ran a number of unlock tools (including the Samsung Galaxy S Unlocker) and think that my phone is unlocked, but the radio shows that there is no connection. When I ran the unlocker, it completes but does not say "its done". I can see that I now have the correct APN setting for Telus. The phone sees my SIM and my phone #. And I have the nv_data.bin file ( was not there before running the unlocker). When I look at the phone details, it sees my SIM, knows my phone number etc. It just won't connect. It also has the correct APN settings. If I try to dial a number or use the data, it does not work. Wondering if there are other settings I am missing?
I think the issue is that the sim only runs on Telus 4G and does not fall back to 3G (what the phone is capable of), but again, this is where I am green. I don't know how this works. Does the phone 'ask' the Sim to fall back, or does the network and Sim dictate to the phone what network it will use?

Just a quick question,
I received a galaxy s5 for work today and it is the att version, if I unlock it and use it on tmobile, does it support the same bands as the regular tmobile branded one?? Like LTE and hspa+ 21.
Thanks for all your help ahead of time and tend apologize if this has been posted before, I tried looking for something similar but was not able to find anything.
I have a AT&T Galaxy S5 unlocked. I put my friend's T-Mobile sim card in it and everything worked even LTE without changing anything (APN), it changed automatically. My brother has Claro (by the way I'm in Puerto Rico), with that one I had to change apn's manually to get data working.
I'm freed my AT&T S5 for use on T-Mobile last month and it works just fine. Didn't have to modify any APN settings either as the phone was able to pull it off the T-Mobile SIM.
In all freq's? AWS as well?
SAMSUNG-SM-G900A, with 128gb SD & Rooted.
That's what I'm wondering. I know LTE will work fine. But what about AWS and hspa.
