Xperia play 4g on tmobile usa

Hey I was wondering if u unlock sim card on the at&t xperia play if it will connect to tmobiles 4g or at least the 3g, I will be gettin the r800at soon and wanna know if anyone has it on tmobile and if they are getting 3g or 4g.
If someone already posted this I'm sorry I searched but couldn't find anything
Thanks

You'll be getting EDGE or 2G whatever you want to call it. T-Mobile runs on a special frequency that AT&T doesn't.

That sucks that's the reson I wanted the r800at ohwell thanks for the info

Hope 3g or 4g will work once the merger happends with at&t and tmobile lol

T-mobile in the US uses the same band it uses in the UK. Thats why it differs from the other US GSM networks If you buy a EU device you can use T-Mobile 3G.

I dont mean to rain on anyones parade, but i thought id go and check this out because that didnt sound correct.
Tmobile 3g seems to require the AWS band, no available model of the xperia play carries that band.
Tmobiles setup uses one band for uplink and one for down, not one or the other, these bands being 1700 and 2100, the r800i carries 900/2100 and the r800a and r800at carry 800/850/1900/2100.
as you can see theres no 1700 band available on any xperia play model afaik. so it appears you might be sol sorry :/

Thanks for all the info so its stupid tmobile that sucks they should have just came out with a tmobile one when the one for at&t came out such jerks well at least I can play games lol ill just have to conect to wifi when I wanna download stuff or watch videos ohwell

T-Mobile needs to step up and get OFF 1700! NOBODY uses that freq! I WANT 3G

Hell ya I agree I only got tmobile cuz they had the sidekick 2 back in the day and just never changed kept doin the 2 year contract thing ohwell

When I flashed my R800at to 2 different generic stock firmwares (which changed my model number to R800i & R800a)my mobile connection changed to Edge. It also changed when I went into the settings>network mode& change it to "GSM only". It only went back to H or HSPA & 3g when I changed the APN's & changed network mode back to WCDMA (preferred)/GSM. Does that mean that the AT&T XPlay can connect to an Edge(2g) network but not Tmobile's 3g network?? What if we changed the APN? If anyone tries this please post the results here.

Ok so I was wrong & I can confirm that the Att Xperia Play will not work on Tmobile's 3g or 4g under any circumstances. Only edge/2g data will work due to the difference in bands as was mentioned here.

well... that sucks. looks like i'll be getting an amaze 4g when i get back from Africa in spring!
(i only ordered the no-contract AT&T xperia play 4g to use on the "orange" network here, i don't want to have AT&T in the states. only t-mobile and verizon have 4g in my area, and i want to keep GSM for next time i travel, so t-mobile it is)

[Q] Unable to use UMTS Mode (ONLY GSM WORKS )

Hi all
I just recently acquired a INC 2 Love the phone by the way and am located in INDIA
I'm running a r1 rom which offers full GSM functionality
SIM: TATA DOCOMO
The issue I have is
I can connect to GSM only Mode , but when I try GSM/UMTS or UMTS Only , the phone cannot cannect to a network.
The phone is SIM unlocked and in GSM only mode I can call/sms/data fine
My service provider uses the 2100 mhz band so obviously the INC 2 supports that, I have searched and lot and have tried various ROMS, but unable to narrow down a solution
i have tried the *#*#4636#*#* mode and even there only GSM ONLY works
NO GSM/UMTS , WCDMA or anything
Basically I cannot connect to 3G
Any suggestion guys

bump guys...... 98 views and not a soul to reply

Had the same problem, couldn't find a solution. Bump!

Have you try manually entering the APN (access point network) for your carrier? That might help.

Yes I have, pretty much tried everything.

yes the APN is the same for both GSM and 3G
It just wont connect to a 3G network... only works on force 2G ie GSM

That is kind of weird. Does Tata only uses 2100 mhz? Maybe try updating the radios? Does the stock rom also not picking up 3G?
I'll be traveling to Hong Kong in 2 weeks and there uses 2100 as well. Let me see if I can get 3G and will let you know. It's hard for me to test UMTS on my DINC2 here in US coz I could only get EDGE from TMobile or AT&T.

All Indian networks use 2100 ... Yes it did not work on stock either ... I'm wondering if band unlocking is needed ..

Help needed: trying to mod my notification bar

I have a t889v running rooted stock 4.4.2 build #kot49h t889vvludnh2, which is the newest build for my phone, i'm trying to mod the battery percentage, i want it to be larger in size so i can see it better. I have tried various mods on the exposed installer i.e. wanam etc. none seem to work, so i would like to use root explorer and change the setting in build prop, the problem is i don't know where to look. if anyone knows where i need to go and what lines to adjust it would be much appreciated. thanks in advance

Do you happen to know what is new with the t889vvludnh2 ROM? I can't find any information anywhere on this update. My assumption was that LTE was enabled. But I am not sure.

i don't see much deference between this and the last rom. I don't see LTE anywhere in the network selection it's still gsm or wcdma
edit: just went into service mode and there is awhole bunch 0f LTE bands, so it seems we have LTE now. For service mode type *#2263# into the dialer and you should see a screen come up with all the band selection. i'm on wind so we do not have LTE service so there is no way to test if LTE works.

I have a windmobile T889v unlocked as well. I am currently in the states and I tried a T-Mobile sim card and did not get LTE. Only 3G. Maybe the LTE bands enabled on our phones are only for the videotron LTE bands?
Hopefully, someone on videotron can chime in.
I will try to get hold of ATT sim card to try.

Which APN did you use? Which part of the US were you in? Not all areas are covered by LTE service.

I am in LA.
It was the APN that was pre-programmed into the T-Mobile sim card. I didn't modify anything. My buddies Nexus 5 was getting LTE and he didn't program any APNs either.
While at the same location when I swapped it in my T889V I only saw 3G (in settings > about I saw HSPA and HSPA+). But def not LTE.

I got a hold of an ATT sim card with LTE service, and only got 3G speeds. Tested the speed on the T889v and an LTE enabled phone with the speed test app. So on T889v def 3G(HSPA) speeds, while on the LTE device LTE like speeds.
Anyone know which LTE band videotron enabled? I thought it was Band 4 (AWS band).
The only other thing I can think of is that the I am using the Windmobile firmware update for T889V and perhaps the version for Videotron is different even though the baseband is the same version.
I had been assuming that Videotron, WIndmobile and Mobilicity were all using the same firmware since the baseband is exactly the same.
Anyone with Videotron T889V with stock baseband upgrade getting LTE speeds?

My phone will only work with GSM.

My internet works only with GSM.
When I change to LTE / 4G it will not work.
I flash back to stock.
It has worked LTE 4G earlier.
I have the correct APN set.
Could it be a setting in my phone or hardware?

Issue connecting to 4G

So a mate has a P2 and can't seem to get it to connect to 4G. The SIM card and network is Vodafone UK.
What I know/have tried:
- SIM in both sim slots will connect to 3.5G (HSDPA) on Vodafone network
- A different SIM (Three UK) did connect to 4G in the SIM slot 1 (did not try SIM slot 2)
- Settings says 4G preferred network is selected
- By typing *#*#4636#*#* into dialer and going to phone info displays LTE is selected as one of the preferred networks
- The same SIM (Vodafone UK one) connects to 4G in his old phone and has done in all his old phones
- APN settings are correct, verified by Vodafone support plus myself looking online
So he talked to Vodafone support again today who said try speed tests in 3 different locations and report back. He has done 1 which is 14mbps down and 3mbps up which is slow for 4G (I get 64mbps down and 24mbps up, different network but shows his is slow and likely not 4G). Similarly we we know the device can connect to 4G from using the Three UK SIM.
My gut instinct is it's a network issue, all device settings seem okay, nothing is screaming out of place. The issue though is that the SIM has connected to 4G in his other devices so confuses me.
So, I'd love your thoughts and inputs on this. Any suggestions welcome that may help! Thanks!

I dont know the device or network specifically But I know that the device has to support the same lte bands that the carrier broadcasts in LTE in that area Just because the carrier broadcasts say 900mhtz in LTE, if the device dont support 900 in lte then it wont get it. I have had cases wher 3g is the same freq as 4g it still wont pick it up If you get what I am saying. May be a issue or not.

to further add he might take one of the old devices and use a signal catching app to see what lte bands are broadcasted in his area then compare to device

Thanks @TheMadScientist, all suggestions welcome still. I'm gunna continue to keep an eye on this, research answers and send him a link to this so he can test anything on the device.

We get this issue a lot using sprint phones unlocked international gsm. A lot of carriers seem to not use the same lte bands.
Then naturly verizon devices come gsm unlocked but verizons radios are crap and do not pick anything up half the time. My veriz g5 can get lte next town over cause they use a supported band and no towers near me use it. So i get 3g. And a lot of h h+ i ise lte discovery as the app on mine.
Just hope this isnt his issue as its a harware compatibility .

So I checked the network and the device (on GSM arena) and it seems 4G bands are supported. But I'll try that lte discovery app with him soon you mentioned and see what results that yields

@matt4321
http://www.techadvisor.co.uk/how-to...r-phone-is-supported-by-your-network-3597426/
You should check the manuals if there is support for 2600 frequency on phone.
Maybe the phone supports 800/1800(cos 3 is on 1800) and you don't have 800 band in area.
You will have to contact Lenovo and ask them to change baseband or whatever...
or Perhaps get a new phone with support for 2600

Had the same problem using a LG G3. I tried this App to trigger LTE only. Then the Phone connect to the LTE network.
