[Q] G2 on AT&T?

---

Hey guys, new to Android and T-Mobile. I got a G2 last week, and I live and work in kind of a fringe area for T-Mo coverage. AT&T has good coverage out here, but the G2 doesn't roam over to ATT, I can't even register on their system when I select it in the mobile networks settings. My question is- how can I set the phone to roam onto their system when I lose T-Mo coverage? (I have heard that T-Mo can roam to ATT on EDGE). Thanks!

As far as I know, the only way to use AT&T on the G2 would be to SIM unlock the phone and use an AT&T SIM with an AT&T account. The TMO SIM won't just allow you to roam because they don't have a reciprocal billing agreement --- though I am no expert on this.

I believe, though I could be wrong, that the G2 does not have the ability for 3G (UMTS) data on AT&T. As you stated, if you could connect to the network, Edge should work.

One solution would be to switch to an AT&T SIM and use the Samsung Vibrant, which has the ability to connect to one of the two AT&T 3G bands. Of course, if you want to use AT&T regularly, getting an AT&T phone would be a better solution. So, for you, unless you want to switch to AT&T, wifi might be your only solution.

Ugh! That is exactly what I was hoping I wouldn't read lol. Well, I do really want to stick with tmo, just wish my phone would auto roam to att when I lose the tmo signal. Thanks for the reply!

I asked around at work a bit, and there are cases where you can roam on AT&T's network. These cases exist in areas where T-Mobile has not, cannot, or will not build out a network. In these cases, they contract with AT&T to provide their customers with network access. Some phones will show roaming, but I think the software, at this point, has made it a seamless experience, and you don't even know you are attached to AT&T's network. For billing, purposes, if you have a national plan, you are not roaming.

This doesn't help you, but I wanted to clarify my blanket statement above.

Check out the coverage map (Select NO for Are you a Rep, then go to the Data Coverage Map):

Unfortunately in your area of CA, there is no roaming partner.

The only roaming in CA is in some parts of N. CA up Hwy 1 and 101, towards the Oregon border, and in the 395 corridor.

I'm thinking of upgrading from my HTC Rhodium on ATT to a Desire Z (also on ATT). Is there anything I should be looking for to make sure it will play nice with the 3G network?

Thanks

You'll need to buy the Canadian version of the DZ (from Bell Mobility).
