[Q] Roaming on AT&T - HTC Amaze 4G

I've noticed that when I enter a T-Mobile 'dead zone' with my T-Mobile Amaze, it doesn't roam to other service providers despite enabling the roaming option.
My previous T-Mobile phones would allow roaming to AT&T, including data roaming, provided that I was in an AT&T service area, but apparently the specific SIM card provided with the Amaze does not allow roaming to AT&T. I even tried to force roam to the specific carrier, and a notification pops up saying that the SIM card does not allow connections to this network.
I find it strange that I was able to roam on AT&T before on my previous phones (such as the G1), but now I am not able to do so.
Any insight to this? I doubt that SIM unlocking the device would fix this. Maybe it would?

I also have been wanting to bring this up to tmobiles attention. Not sure what you guys mean that Amaze not allowed to roam? My phone is unlocked and inserting an att sim only connects to att not tmobiles network. So that is not roaming.

I've noticed that the older T-Mobile SIM cards were able to roam (especially on the AT&T network) but it appears that the newer ones prevent that capability.

if y'all aren't able to roam with your Amaze ya need to contact TMO. I'm a long haul trucker (border-to-border mostly east of the I-35 corridor) and I have no problems connecting to other networks when outside of a TMO coverage area including connecting to AT&T (huge areas in rural OH and WV) even connecting and getting 3G speeds on AT&T's net.

Same! When I visit my parental units in NE Ohio I roam on AT$T almost constantly with my amaze. Usually what I have to do is enable/disable airplane mode and it will connect automatically. (You can't just manually select AT$T, it has to be done automatically by the phone, otherwise you'll get a registration error)
Hope this helps! Otherwise you should just call TMO and complain.

Does roaming charge you extra on your bill? And do you notice data speed differences while on other networks? That's my noob question for the week.

In 8 years I've never been charged and I drive all over the country. Some of the towers won't let me go over 2G and some let me on at a slow 3G (I have noticed their 3G isn't as fast as ours)

---

For calling and texting? No charge at all. Just your normal limits on minutes, etc. As for data, they implemented a policy that depends on how much data you have. I get 2gb of 4g, and for my plan I get 50mb of data roaming, after that they cut you off from using data while roaming. You will still be able to do calling/texting however, and you will/should not be charged for roaming within the country under any circumstances.
Oh, and... BAM!

Yo what's the update? Unfortunately I'm in LA, Cali area and have great reception unfortunately I can't test or force my phone to roam. I would hate to wait till I leave town to try testing this whole roaming thing.

Okay when I try to use att through this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Then this error comes up:
Just giving you an idea of what I have.

Did that. It didn't change anything. I did it several times. Strange...
But yeah, I noticed that from what he said, I can't just select other provider.

Yeah I'm on the same boat. Anyone know how I can test my roaming? I remember there used to be an app for cdma devices a while back.

Hmmm. So just to see for myself I threw my T-Mobile sim card into my old SIM/BL-unlocked Sony Xperia Play 4G from AT&T, and look what I did. Turns out it really is the sim card blocking access. It seems Tmo only lets you roam when they see fit, as in, you can't "choose" AT&T's network, it just becomes available if your Tmo network is unavailable for a length of time. I think. Maybe.

I'm wondering. Is your T-Mobile's SIM card a WiFi calling capable SIM card? I'm suspecting that the newer cards do block access. When I had the old (non WiFi calling capable SIM card) on my G1, I could choose which carrier I wanted to use, including AT&T if I wanted to roam. This was nice, as sometimes I'm in a location where T-Mobile has like 1 bar of GPRS/edge service, and the AT&T would have several bars of 3G service.

Yes, I have WiFi calling through my sim card. It doesn't charge me minutes ^_^ I wonder why they would do that, though. Very odd.
