For some reason the galaxy s2 is only on Edge, i never see 3g or the H
The baseband is galaxy s2 baseband I9100XXKH3
Is this the problem? i know i should have 3g in my area but when i check "about" it only shows edge
Whats wrong with the phone?
Thanks for anyone that can help
Two things to check would be to see if your provider supports the 3G band that the phone supports and also to see if your Wireless Network settings are set properly. You can choose auto to select both bands or select GSM only.
Then, try changing radios.
If your sim is old get a new one. Just ask your carrier you should get one for free. The old sims don't support UMTS.
Hi guys
I want to ask is it possible to change the at&t modem to a t-mobile modem so i can use 3g/4g on tmobile network if not just tell me im curious.
I saw this happen to the galaxy note and was wondering if it possible to do it on this phone.
thanks
Nope. It lacks the bands required for T-Mo frequencies.
I have a I9300 S3 international version. I recently Shifted to the US and am not able to get 3G connectivity. I can see only EDGE network. I know its got something to do with frequencies, because I have the APN etc correctly set up. My only question is will it ever work on 3G on T-Mobile? Is it fixable by flashing any modem?
P.S. I'm using Cyanogenmod 4.4.4.
While I was working in Korea, I bought a Galaxy s3 SHV-E210 (Korean Model) cell phone. When I bought, I was told that I would be able to use it over here in the States. AT&T was able to put a sim card and activate it on their network, however I only get 3G. The Sales rep told me that the bands for 4G/LTE are different in Korea than stateside carriers, so I may, or may not pick up 4G/LTE. I've done some research and found that the band in the phone can be changed using certain codes. When I enter *#9090# it brings up a menu, I've tried changing some of the 4G/LTE, 3G options in that menu but I never get 4G. I know how to root and put custom firmware on devices, so if that is something I need to do then I am comfortable with that. Can this phone be changed to get a 4G/LTE signal? are there any more "codes" that I can enter in to get any other options that will help me? has anyone here ever change the band on their phone to work on 4g? Thank you for any and all help.
AT&T uses LTE band 1 for service.
since E210S only supports band 3 and 5, and 3 and 8 for E210K, there's no way to access AT&T LTE network with your device.
It is reported to support band 1 for newer devices like S5 and G3 and AT&T LTE devices might work in Korea since May 2014,
LTE won't be available with Korean S3 in US.

Not including myself, the rest of my family is on Verizon. My daughter recently upgraded her S3 so I have it now as a handmedown. I have AT&T
and have been using it with their sim. (Verizon doesn't lock their smartphones) I get normal voice coverage but can't get anything more than
edge on data. I have 2 APN's programmed that I found here. One is HSPA+ and the other is for LTE. If the sim is in an AT&T phone, I get LTE
coverage but in the S3, nothing more than as mentioned. Is this because AT&T doesn't have the IMEI registered on their end or is it something else?
I'd really like to get more out of this phone. Any ideas?
Thanks ahead of time,
Todd
