No, it doesn't work. It's only unlocked for international SIMs. There's a thread here somewhere about people trying/failing and talking about buying a Rogers one in order to use AT&T with their LTE.

Thanks man. On the other hand when I pay a full price for the phone should they take the lock off it? I believe it must be a way.

God you would think they'd carrier unlock it, wouldn't you? Or maybe Motorola directly? Have no experience with this at all.

No, not possible.

So, is the code embedded in device's rom not to take any att, tmobile or sprint cards? Or is it managed by some kind of chipset? If the phone is unlocked there should be no simlock at all. Anyone has any technical knowledge about it??

It won't even work roaming with a 3rd-country SIM installed... I tested this weekend in Phoenix with my Telcel (Mexico) sim in there. It saw AT&T and just barely registered before the phone went to "emergency calls only." I know it connected for just a moment with Telcel because I later - with the Telcel SIM back in another known-good GSM phone - got an SMS from the network suggesting I buy one of their exorbitantly-priced roaming data plans. It was time-stamped at the same time I was trying to register on AT&T with the Telcel SIM in the Maxx HD.

I'll give it a proper try inside Mexico this weekend and see what happens. I suspect it will work. I'm a little bit surprised it wouldn't even let me roam, the block appears to be at the network level.

Thanks man. Keep everyone posted when you test it down in Mexico. Still wondering why don't they let us use it on any network.

It works great. I had to manually enter the APN information as expected. In network settings I had to force UMTS to get an HSPA connection. I'm posting from Mexico now... display shows H+ at the top. I only see the carrier name when I swipe down from the top of the screen.

I actually sat in a parking lot on the US side for half an hour to get the settings right.

Were you connected to a Mexican carrier? Or US Tmobile?

 

[zowwie]

No, i parked close enough to the border to get a Telcel signal. I wanted to do it while I was still in the USA, ya kinda have to watch your back in some border towns.

I didn't want to have to keep one eye on the street, and needed Google maps to be working the moment I crossed.

I didn't attempt to connect to an American network.

The mobile hotspot feature does not work while roaming, the phone's firmware still tries to check with a Verizon server for authorization. Of course it can't connect, so no hotspot.

so does it accept foreign sims

 

[zowwie]

Not to roam on a US network. Foreign SIM on foreign network works fine, just configure data APN's and you're good to go.

[zowwie]

It is some kind of lock at the radio firmware level.
Same thing with the OG RAZR - the bands are activated but it is not accepting American GSM sims.
