Hey People,
I bought 2 months ago my Galaxy Nexus on Play Store for this wondeerful price they sell it.
My plan was to bring it here to Brazil and, of course, use it.
But, I used it on T-Mobile network while I was in the USA in Maryland area. The results where very good... Almost always having 3G signal and pretty decent speeds testing on speedtest app.
When I started using it here in Brazil, I had some issues related to HSPA+ speeds.
My carrier (Claro BR) does support HSPA+(some carriers here, don't), and sometimes, I think, the phone just forgets to use HSPA+ and keeps using HSDPA...
I can reach up to 4Mbs on HSDPA and always between 4-8Mbs on HSPA+.
What I normally do is turning on and off airplane mode and the phone starts using H+ again.
I am using I250UILE1 radio and CNA 05192012 nightly w/ 1344-384 Trinity kernel.
I forgot to say that when I turn Wifi off and automatically let my phone connect to DATA connection it fastly connects to HSDPA switches for a little time to UMTS and then switches back to HSDPA and no signal for H+. And I again have to switch radio off and on (airplane mode).
I think I tried almost everything...
I just unlocked my lg nitro hd and i either have no signal or 1-2 bars, rarely 3 bars. I also have to search networks and register on t-mobile everytime my signal is gone.
Signal always goes out in about 2 mins and Wifi is working fine.
Network mode is set at LTE / WCDMA / GSM
I'm running cyanogenmod 9.0
Baseband-V10j
I also resetted it to stock and i still get the same signals.
When i slip the sim card into my nexus one, i get 4 bars.
Any solutions?
thanks
Nitro HD doesn't support T-Mobile 3G frequencies, so you will only be able to connect to 2G towers. I'm assuming the distinction is that the Nexus One is connecting to a 3G tower which is closer to you.
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

Do you live nearby a 3g tower?

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?
Good am guys, I'm from the philippines and I have a samsung galaxy s4 mini i9195t 4g LTE came from australia with vodafone sim last year. I'm using our local simcard. Can't access free data, 3g and 4g LTE. Upon researching i saw that I can only access 2g network which is the reason I'm here
Can anyone. Is there any way that I can access 3G and 4G LTE signal? I never root this phone nor unlock and the system was never been touch. When I got it I just insert my local sim.
Please help me guys I've been searching for the right forum for the solution of this problem.
Did you search at phone's settings for 4G or 3G? Maybe it's switched to 2G.Your SIM card is 4G?
Yes I tried to switch it to LTE/WCDMA/. WCDMA/GSM. WCDMA. It doesn't receive any signal at all. Even though im near from the 3g or LTE network. I can't even use surf promo when I registered to a surf promo here it always eat my balance. And i am not receiving 3g or 4g. It's just letter E always.
I recently purchased an HTC 10 from UAE. I am experiencing problems with LTE signals. I am running stock Android Nougat 7.0 with January 2017 security patch. If i go to some area where there is no LTE coverage then my phone data connection doesn't work which is perfectly fine but when i go back to an area where there is strong LTE coverage my phone doesn't get back LTE signals. I have to turn the airplane mode on and off in order get back LTE signals. Phone itself should get back LTE signals automatically when it is in an area where there is strong LTE coverage. If i dial *#*#4636#*#* and go to Phone information it says Data Technology is unknown until i turn on and off airplane mode. I have triple checked my APN settings they are perfectly fine.
Also sometime when i am in an area where there is strong LTE coverage even then my phone automatically stops getting LTE signals . My friends are using the same network that i am using on different smartphones and they're not experiencing this kind of problem.
Does anyone experiencing this kind of problem?
