My Chinese intern said that you can run this phone on TMO's network with a pre-paid sim, but AT&T requires "a lot of work."

 

She has friends from China who are using this during stints in the U.S.

First u have to make sure it supports USA LTE/wcdma/gsm bands. A lot of devices do not since they were designed for Asia.

 

Then you just manually edit the APN for the carrier.

Yeah, sbolen's intern got it backward.  The handset is far more compatible with AT&T than with T-Mobile.  But we are talking only GSM/W-CDMA.  No LTE whatsoever.

 

I am not sure what the fascination is with Chinese people wanting to use their Chinese handsets here.  Get an American market or international handset.

 

And does this handset have an FCC ID?  Is it authorized for use in the US?

If Sprint would allow unlocked phones it would work on there band 41.

Sprint will sometimes add unlocked phones now. But this one only supports one Sprint LTE band and no CDMA. So this one definitely isn't going to happen.

It'll work fine on T-Mobile, AT&T, and their MVNOs.

 

T-Mobile uses 1900MHz for both 2G and their 3G/4G HSPA+ network, while AT&T uses both 850MHz and 1900MHz for both 2G and 3G/4G HSPA+. 1700MHz 3G isn't that important for T-Mobile nowadays, they shifted that to 1900MHz to make space for LTE - in some markets 1700MHz 3G has been completely shut off.

 

As noted above, s/he will just have to edit the data/MMS APN settings so data and picture messaging works well.

Because of Tmo aggressive refarming for LTE, I wouldn't quite characterize it that way. I would say it currently should work in all of Tmo's footprint, with some areas having limited data performance that will only get worse over time without LTE.

Yep I know that. I was just pointing about that band 41 would be the only thing that would work. Just didnt explain it as well as you did.

For St. Louis, it's going to hit AT&T B2 and B5 HSPA and T-Mobile's B2 PCS HSPA. And in AT&T's case, that PCS HSPA could be going away some day. I have had a gut feeling AT&T did their spectrum swap there with Sprint so they could go to 20x20 PCS LTE somewhere down the line. They probably don't have enough HSPA PCS cleared for it yet, but if I had a Galaxy S6 in STL I'd be checking service mode to see what the PCS deployments are. In Cape Girardeau AT&T is already running 10x10 PCS LTE aggregated with 5x5 B17. Now in St. Louis they have a much better spectrum position so they can aggregate B2, B17, and B4 when they kill off Cricket CDMA if they haven't already. My advice to your Chinese buddy - get a Sprint device. But if he must use a GSM carrier AT&T has better coverage especially in building, he needs a device custom fit to this market.

    • T-Mobile Will Soon Prevent Early Payoff Of Phones Receiving Bill Credits If you finance a phone with T-Mobile it will remain locked until paid off but now you won't be able to pay off early. If you don't currently purchase your phones from the manufacturer here is another reason it might be a good idea.
    • Was in Red Hook again and I swear there are more Link5G sites as there are Verizon, T-Mobile, and AT&T small cells combined in the entire neighborhood. It seemed like every other street I turned down had one installed. Hopefully carriers will start hopping on them soon. Seems like a lot of effort to go through for no one to use them.  — — — — — T-Mobile converted the Sprint site on top of NYU Langone Brooklyn in Sunset Park. I first mapped one sector of it back in November 2023 but I thought it was a small cell so I never pinned it but I ran into another sector today which caught me off guard. I'm unable to find a permit for the conversion so it's definitely a surprise. There's another T-Mobile site 1 block away that T-Mobile initially installed back in 2019 so I'm kinda surprised they're keeping both considering the Sprint conversion is on a much taller building and could potentially provide much better coverage to the entire area.  — — — — —  Old permit for this new install expired but a new one was recently issued. It's gonna be similar to the site at 360 Forman St in Brooklyn Heights. Permit calls for only 3 antennas to be installed so I'm assuming it gonna be Band 2/41/66 and n25/41 only which is a bit of a downgrade from the now decommissioned full build that was on 871 7th Ave but in it's current state the nearest macro is a few blocks away and a small cell at Broadway and 55th is doing a lot of heavy lifting in the area so anything helps.  
    • Still not seeing any ULS postings for pending T-Mobile UScellular merger in Dane county Wisconsin.
    • Came across another Crown Castle Solutions multi-tenant oDAS node in Brooklyn. Located at 40.7002286, -73.9612666. Nothing on T-Mobile or AT&T so I'm assuming these are all Verizon nodes that Crown Castle is anticipating another carrier will hop on down the line.
    • Same with factory unlocked
