I bought an unlocked Sony Ericsson Xperia Play R800i from Amazon to use with a Straight Talk sims card; however, I'm unable to connect to 3G. The phone only shows an Edge connection. Straight Talk specifies that the phone must operate in 850 and 1900 MHz bands. Here's what the Amazon page says about my phone:
This phone can be paired with 800/850/1800/1900 MHz UMTS/HSPA 3G networks in the United States (as well as 900/2100 MHz 3G networks found around the world, including in Europe and Asia). In areas not served by a 3G network, you'll continue to receive 2G data service via the EDGE network (depending on network compatibility).
I might be wrong, but doesn't that mean it operates under Straight Talks specifications?
hi friend...i've been following you.

i have the same issue but with my carrier offering 3G at 2100 Mhz which is Xperia Play supporting. When searching for carrier it shows me just 2G provider, non 3G. when WCDMA only selected, i lose signal. I am in coverage of 3G and my plan is supporting it.
Could it be hardware issue? i did factory reset but still having this issue. Connections just through EDGE, GPRS or Wifi

I purchased an R800at from Amazon, which, according to that thread, should be able to connect to 3G correctly.
I've unlocked the bootloader, and flashed CM7.2 onto it, and I'm still only getting an EDGE connection. It shows a second connection under the "Network Operators" menu in the mobile settings, which, when I ran the stock ROM, was listed as "3G" but it always defaulted to the "2G" listing.
I live near a large city, and have gotten 3G on other carriers, and even 4G on a friends T-Mobile phone. I think I'm running the T-Mobile based SIM card, because the AT&T APN settings don't work with it, and the SIM came with the T-Mobile settings, it's even labeled in my APN as "Straight Talk T-Mobile" but I still only get EDGE.
I don't know much about straight talk, but is your Sim a 3G one? I had this issue a while back where i could only connect to 2G networks but then went to my carrier's store, told them the problem and they ported my contacts and number to a 3G sim and its worked ever since.
It may also be worth trying to get the APN settings from your service provider to see if this solves the problem.
I have an unlocked R800at (AT&T) that I am using on T-Mobile. Now where I live it shows that people have already reported getting HSPA+ on unlocked AT&T phones.
I have all the correct APN settings, however I always get 2G (Edge). But if i got to:
Wireless Networks
Mobile Network
And select search, for me it will bring up T-Mobile 2G and T-Mobile 3G as options. I select the 3G and it will connet and I will get HSPA+ (download of up to 7mbps, 3-5 up) for anywhere from 30 seconds to 5 minutes, then it reverts back to 2G. Its not a huge deal for me as when I was on VZ I had edge like speeds, but to be honest if I can HSPA+ then i would like to have it but I cannot find a way to get it to stay on 3G. I have used 3G speed tweaks, trying different apn's... nothing. Anyone have any ideas or suggestions?

I'm not entirely sure. I bought it on ebay, it's listed as a T-Mobile SIM card. It was a standard size, that the seller cut to micro. I have to put it in an adapter to use it with the phone.

hi, i have the same problem. r880i, it works well on gsm, totally unstable under wcdma..the "funny"thing is that i can't make calls nor text when it gets no signal(with the yellow triangle at top left),but i have data connection(i can install apps from store,browser youtube facebook works ecc) and i get mm#6 error sometimes(the phone in not stolen or whatever lock). all working well when set to gsm; if set to wcdma/gsm, or wcdma only it does the above mentioned behavior. i've relocked bootloader and repaired with seus and am currently on stock 2.3.4.. any fix or know issues?

I'm trying out a new TP2-CDMA from Telus (Canada) and this is by far the best system I could ever try in my case. I've always been a GSM user (since 1994) mostly because it gives you the latitude of using what ever device you want just by inserting your SIM card. so I got the Phone Inserted my Rogers SIM in it and it got me on the Rogers network right away I then activated the phone on the Telus network and it is also working fine... of course...
But the best thing is that I set it on "Global" network and it stays on GSM (Rogers), and when I get to an area where there is no GSM signal it switches by it self to the CDMA (Telus) network!!! this is amazing! NO MORE DEAD SPOTS! Of course you need to have two Service contract from two different service provider, but if you absolutely need to get service in areas where your current provider does not offer any, well it sure beats the hell out of having two different cellphone in your pocket... I have set my main cell number to transfer to the other on "No Answer after X # rings" and I get all my calls no mater what network I'm on!
The only down side to this TP2-CDMA Unit is that Telus got rid of a bunch of stuff that is in the TP2-GSM... like the GPS for instance... Well I guess you can't have it all...
Just thought I'd share my joy...
The GPS is working, actually it works pretty well.
rick#2,
You are right, the GPS works.
I was trying it with Google Maps and could not make it work because GM does not seem to be able to get the data connection on the GSM network to load the maps and I thought it did not have the GPS but it does and all other Maps SW works on both GSM and CDMA, except GM that does only work on the CDMA network on this particular device...
I've been using the GSM connection for the TP2 down in the states and I stay purely CDMA up here in Canada. I'd like to say that HSPA works on the GSM network but no dice... unfortunately... don't know why.
Hopefully the 850/1900MHz bands that are possibly physically present on our Telus TP2s can be made available somewhere down the line. It's too bad they aren't up and running now, since I'm headed down to Mexico in a week and they are all 850/1900 down there for their UMTS network.
Yeah..
I know what you mean
Perhaps this one can solve the issues....

Hi Everyone,
I wanted to find out oif any LUMIA 900 users in BELL are able to see LTE.
I bought the LUMIA 900 from ROGERS Friday afternoon and Saturday I paid 16$ to unlock code.
I went to bell and change the SIM card to be LTE supported. (I had a iPhone 3GS)
I successfully unlocked the phone an put the new card in,BUT I RARELY see LTE.
I mostly (95%) see 3G and YES I looked at the BELL LTE Map in their website. Even though I am currently located (work) within the area I never see LTE.
I called BELL Canada and they havent been able to give me much information.
Setting on my phone are:
Active Network: Bell
Data Connection: ON
Data Roaming Option: Roam
Hieghest Connection Speed: 4G
Network Selection: Automatic
APN: pda.bell.ca
User Name : Left empty
PAssword: Left Empty
Proxy Server: Left Empty
Proxy Port: LEft Empty
Any other Lumia Users with Bell Canada???
Your help is much appreciated.
You must call
Hi,
I had a similar problem with my Ipad 4G but i found the solution. You must call bell at *611 and get thru to tech support! Once you are thru tell them that you have an LTE capable phone and get them to add LTE Provisioning to your account. After they do that restart your phone and LTE should work. (It may take a while to connect to the LTE network)

Bell LTE is crap. Alot of areas marked on the coverage map for LTE dont work. Travel around the city and see if it works in other areas. For example, Keele and Steeles area in Toronto (not sure where you are) is LTE and I get my LTE signal there. If you still dont then try the above post.
Similar situation here with Telus sim. I get LTE but much more often phone sticks to 4G. In most cases i see only one bar signal. There however have been places where I get 2 or even 3 bars (woodbine and hwy7) only once I have seen 5 full bars of LTE - in the Weston Rd & HWY7 area.
I haven't called Telus about provisioning, all I did is to swap my SIM for a V3 LTE one.

Was yours Rogers too or AT&T?
Similiar situation here. Except I'm using the Titan 2 unlocked on Telus. They share the same networks at Bell from my understanding and same for LTE. I popped in my LTE enabled sim and so far I have yet to see LTE appear on my screen. I live 3 min Yonge/Dundas and work at Yonge/King and have never once seen LTE appear. You'd think being in the heart of the city you'd have LTE 95% of the time but so far nothing.
I tested download speeds and so far best I was able to get from Telus was about 5mb/sec. Not this 21mb/sec that LTE promises. Even on wi-fi at home with the top Rogers high speed plan I only got 9mb/sec.
Did you get the LTE provisioning?

Hey Pistol44,
The same thing I said above should apply to you! In most cases just getting an LTE sim card is not enough. You must also get you carrier Bell/Telus/Rogers to add LTE provisioning. I work for a company that sells Cell Phones on all the canadian carriers and I see issues like this all the time. A quick call to tech support should fix this!

I haven't called them for any provisioning. I get LTE on the Lumia but seldom and almost always 1 bar only. Interestingly the same sim placed in unlocked Sierra Wireless AC754, LTE holds consistently. Still 1 bar, but stays.

Thanks for the info and I did follow the suggestion. I spoke to Telus support and had a lady guessing all kinds of things for me. Clearly she wasn't familiar with Windows Phones in general. She had me try adding an invalid APN, then turning data on and off. She claimed there was nothing to provision on her end. Eventually I gave up with her and tried a hard reset. But still nothing. I edited my APN last night to isp.telus.com (only added the "i"). No change.
Then by some type of black magic LTE showed up today while I was at work and it stayed on my phone for about 2-3 hours even after I left the office. Well now I'm back at the office and it's on 4G again. Funny how I can be in the same spot where it's LTE one moment then 4G the next.
She probably did something!

I would not be surprised if she did something. It usually takes 16 to 25 hours for a provisioning profile to start working. Sometime they do call it something else.
I should also mention since then I've been getting LTE to show up about 75% of the time or more now. Sometimes it goes back to 4G and then I do a soft reset and it goes back to LTE in a few min. Not sure why but that fixes it.
Got my zl today excited then let down by problems with internet, so i insert sim and it picks up tmobile and auto download settings then when it start downloading google play apps it hangs.

I know the ZL (6506) is capable of working with T-Mobile's new LTE network, but my question concerns the IMEI number and your account with T-Mobile. On AT&T, your account has to have an IMEI number that is known and recognized by AT&T so as to enable LTE connectivity. Is this also the case with T-Mobile??

The info or where you got your info is incorrect. you DONT have to have a IMEI number that is known to AT&T to have LTE. I have changed phones prob 20 times since I got my first LTE phone and NEVER had to change it again.
You can be on the LTE data plan and everything work fine on a old dumb edge phone then put the sim card back in an LTE device and it still work fine...
LTE worked fine on a Canda Note 2 and One X
Same here. TMo does not care. I just started using my ZL teo days ago, before that was Nexus 4. Just took the SIM from the N4 and inserted in the ZL. All works!

Hey people, I'm seriously considering picking up a Sony Xperia ZL C6502 Black. I'm aware that it doesnt support LTE on either network, but the price is insanely lowwww! My question is, does anyone know what kind of speeds I can expect to see on TMO and ATT respectively? I'm currently using an ATT Gnote 2 on ST/ATT and I have a Nexus 4 as a backup which I use on the TMO $30/"unlimited" data plan. I only point this out to indicate that I don't get LTE speeds now, which sorta makes it a "You can't miss what you never had" type of deal. I roughly get about 14-17mbs down on either device. Is there any chance I'd enjoy the same with the 6502 on either of these plans??? Any help/insight or even opinions, would be greatly appreciated.
The speeds to expect will be the same as you have now.......

i just received my ZL C6502 today and noticed that the data connection does not work at all. i followed the APN settings on the t-mobile link you gave and still no dice (it does show full bars and H+ as you mentioned and when i switch the SIM to my old G2X its on full HSPA+ speed). i left the house and it was running ok suddenly and streamed netflix, etc. but when i went home it lost the connection again. I'm suspecting that this phone does not really work on t-mo's 1700 AWS even though the box says so and that i only got online outside the house because that area is on the 1900mhz refarm. is there any difference to t-mo's AWS 1700 and regular HSPA 1700mhz?! any insight or help is appreciated!!
I have a 6506 on TMo so I am limited in help. However, someone in my office has a 6502 on TMo and it is working fine. He had trouble until he manually set it. Same case as mine.
Perhaps you have a defective unit? Try removing and reinserting the SIM card. Perhaps a factory reset.
I had mine for almost a month and has been flawless in LTE when in DC and HSPA in Dallas.

The 6502 is the same as 6506 but without lte it should work I don't have 1900 coverage and I'm always on hspa and there's no lte were I'm at either. U need to make sure the apn is set exactly there should not be any values under proxy and port also under apn type have it blank that was the issue with mine those three things had values and was messing up internet. Also there's three different apn you have use. 1. Fast.tmobile.com (Lte), 2. Epc.tmobile.com, 3. Internet2.voicestream.com. Give it a try.

thanks for the help guys. ive gathered all that info earlier and did try the three APNs different combinations / proxy - no proxy, etc to no avail. i'm leaning on faulty hardware or messed up radio. i'll just sleep over it but so far its been disappointing :crying: great phone though...
As a quick update I did literally sleep over it and I'm happily up and running with hspa.. I literally left the phone alone overnight lol. Rooted the fone and all I need is to figure out how to get to recovery to put CWM since pressing vol up at boot is not working and flashboot isnt going either (that's for another post). Moody bastard this ZL is.. Anyway Thanks again!

That's the thing you had an LTE phone AT&T had in their system when your account was provisioned for LTE so you never had a problem after that. For those people that have the ZL as their first LTE phone on AT&T they will have to first get the account setup for LTE using a phone AT&T recognizes on their network.
So basically put the SIM in an AT&T LTE phone, have AT&T provision it for LTE then once that's done you can put it in any other LTE phone and it will work fine

I just bought the tab 3 7" T217A from at&t and went to Mexico to use it in 3g but I don't get any data access.
The tab recognize the sim card company (telcel) and the APN values are correct, it's Sim unlocked I suppose.
Pretty much all carriers in the US are locked to their devices. However, that should not stop you from data connections unless the host carrier does not have data or the host carrier uses different frequencies for data. It is also possible you may have to use EDGE and not 3G for your data. My iPhone 3GS worked in Afghanistan on GSM but I was limited to EDGE as they had no 3G. Just a thought. You should go to a local cell phone store and ask about data on the T217a.
Caveat: I do not know the Mexican network nor the device you are using. My comments are just based off of assumptions.
Yes, you are right, I had few phones that appears in edge but can connect tod data but in this case the signal icon appears just the bars but no E icon or roaming.
I think I'll go to a store to check it
So I'm on WIND with the LG G4 (H812). I have unlimited US roaming with them, and just got back from a roadtrip in the United States. I drove from Toronto, ON to Los Angeles, CA and back (in 2 weeks), and got to test the G4 in over a dozen States.
My data was excruciatingly slow. The icon at the top of my phone said I was connected to 3G (never HSPA+ or 4G), but it felt slower than 2G. I couldn't stream music, couldn't watch YouTube. Websites and the Facebook app barely loaded (and photos never worked). Facebook Messenger and Google Hangouts would send, but again, barely. Sending someone a photo using Messenger usually took 5-10 minutes.
This was the same regardless of what State I was in (over a dozen states).
When choosing what to connect to, it always gave me 4 options:
T-Mobile: WCDMA
AT&T: WCDMA
T-Mobile: GMS
AT&T: GMS
I always got the same speeds, no matter what I connected to.
On my old HTC One (M8) on WIND roaming in the US, I was always able to choose if I wanted to connect to 2G, 3G, or LTE. That's missing on my LG G4. The only options I'm given are:
GSM/WCDMA auto
WCDMA only
GMS only
I tried figuring out more information on my connection and bands. I went to the dailer and entered *#*#4636#*#*
A note would pop up that says "This application does not work on this device." and I couldn't see anything past that. That code doesn't work even now that I'm back in Canada.
I'm heading back to the States in a week, and unsure what to do. Is the problem WIND? All Canadian carriers? H812 Bands? Now that we have root, is there anything I can do to fix/unlock this without switching carriers?

Does your plan also include DATA roaming? 4G, LTE roaming? I think it would require adding an APN? Perhaps the roaming network towers can not authenticate your device, ect?
You can use the play store app LTE Discovery, it can show you what bands it's connecting/trying to connect.
Here compare your 812 to 811 810 bands. http://pdadb.net/index.php?m=pdacomparer&id1=8306&id2=8059&id3=8046

Yes, my plan includes data roaming. I've been with WIND for years, and used my HTC One (M8) on exactly the same plan while roaming in the US, and it worked properly. I reached out to WIND and their response was:
"I believe our roaming agreements cover 3G access while in the US."
Like I said, my M8 worked fine at 3G speeds in the past. It's specifically been the LG G4 that barely worked.
I took my Bell G4 to Italy this summer and got LTE in Rome, hspa otherwise. Worked great, just had to enter the apn myself (which I had to do on my Samsung phones travelling over the years).
Have not tried it in the US.
Im with Rogers and had no issues with roaming. I think it chooses AT&T in the states by default.
If I recall correctly WIND doesn't have the LTE band on the G4s. It's missing something. Although based on what youre describing it's like you're on EDGE (2G)
