[Q] 3G

Hi,
i m using my HTC phone in Mexico with Telcel. I bought a 3G package but I cannot receive the 3G and i m only in edge. I ahve done the configuration that i found in various webpage for Android but it doesn t change. The same thing happens with a Samsung galaxy S.. I tried the sim in an iphone and it does receive the 3G.
Is there anyone who knows if there is something t do, to configurate so that my cell can work in 3G in Mexico?
It would be very helpful.
Thanks.
Mike

Maybe your Preferred Network Type is selected Only 2G?

Thanks but i tried in Auto and also selecting WCDMA only but it only receives 2G ...
Celphone is purchased in Europe but 3G works in all other countries out of Europe..

[Q] Can AT&T be used with a Korean Optimus G Pro?

Hi everyone and thanks in advance for your time.
I have an unlocked Korean Optimus G Pro from the Olleh company. I switched providers to AT&T but it seems that the phone doesn't has access to the Data network provided. I have great phone signal but no Data network (No 4G LTE, 3G, Edge. Nothing at all). Everytime I turn on my data I get the message "Connection unavailable. Configure Mobile Network or Wi-Fi settings to download data."
I understand that AT&T is GSM. But this phone so far is only working with WCDMA only. I've tried switching it to GSM or any ways to make data network available with AT&T but so far it is not working. I checked the WCDMA Service settings but no luck.
Can anyone help me with this? Thanks! :good:

I have the same problem! You could solve it?

1. This may be obvious but you do have the sim in sim one?
2. Go to settings / more / cellular networks ends make sure you don't have 2g only selected.

Just update to 2.19.40.22 fw update..it has 3G stability and 3G works fine after this update..if you have older version this problem will persist ..

Same problem in my ASUS ZenFone 2 laser 550kl model finally said that customer care service executors better to check in authorised asus customer service centres the problem may occured due software issue...

Still facing this issue on Airtel Network in India at many locations. The network switches between 3G, H and H+ and hardly pages open up. Also, there are call drops when network switches from 4G to 3G/2G and 3G to 2G.

Not able to access 4g network

I have vibe p1a42 3gb ram 32 gb rom version and not able to connect to 4g network. If searched manually i can see all 4g network signals around me but when I try to register on 4g network signal gets lost and selects 3g network after that. 3g/2g working fine but only 4g giving trouble. Is it about baseband on my p1 .
P1a42_s288_160271_row
Baseband version is mpss.dpm.2.0.2.c1-00131 .
Any help is really appreciated.
