I got a bad ESN on my d2g. Is it bad for global use?
I'm using a forgein simcard from Vodafone NL. but I can't get the mobile internet working. EDGE as wel as 3G and HSDPA doesn't work for me. I will test it with t-mobile NL this weekend. Is this because of the bad ESN or lack of UMTS radio bands?
Any suggestions?
Edit: I already tried a hard reset, sbf and custom rom. The APN is set correctly.
I called vodafone and went to the store but they couldn't help me there.
At *#*#4636#*#* -> phone information -> radio bands -> Only USA band shows up.
Tested with T-Mobile and it works. So going back to the vodafone store.
...try Hard reset, then set Network Mode to GSM\UMTS, and Select Network to Automatic.
For Better GSM signal Select Network to GSM Only. In GSM Only works only EDGE internet connection.
Already tried, but with no succes, thanks for the reply
Have you added the required APN configuration?

well just so you know the ESN is only used on CDMA networks such as verizon, anything else would use the IMEI of the phone which is more of a international serial number so if the esn is bad it shouldn't matter because your network wouldn't even use the esn
I edited my TS, because I forgot to mention what I already tried

I have 9 options there, none of which says "USA band".
Here is the list I get:
WCDMA preferred
GSM only
WCDMA only
*GSM auto (PRL) (selected)
CDMA auto (RPL)
CDMA only
EvDo only
GSM/CDMA auto (PRL)
Unknown
Also - this is called "Set preferred network type", not "radio bands". I don't see "radio bands" anywhere under 'phone information'.
Try to flash the 2.4.29 full SBF. This should reflash radio and everything. Also - 2.4.330 has crappier radio performance when it comes to GSM/UMTS part of the phone. I would recommend you to stay with 2.4.29 if you are not using the phone on Verizon's CDMA
I mean radio bands try *#*#4636#*#* -> phone information -> menu -> radio bands ->
Already tried that SBF I didn't know there was another.
I gave up on the network because mister not so nice at the counter of the vodafone store. He basically said, We don't have it in our system so we can't help you! I switched to KPN NL and I have 3G and HSDPA without a lot of fuzz.
I bought my 1+ from the website and it was working on Wind's network (1700/2100 MHz) until just now. I flashed CM12 nightly and realized I couldn't make phone calls (data and WiFi were fine). So I followed a thread on XDA and changed my band to USA/Europe (*#*#4636#*#*), but none of these have 1700 or 2100 selected. Now, my phone won't detect Wind's network in Settings > Network Operators and data/SMS/voice won't work.
I tried many different modems (CM12, 44S, etc.) but it only shows Bell, Telus, Rogers on the network scan. Any ideas on how to get Wind back?
Update, here's my analysis (this is for CM12 nightly):
In the stock 44S ROM there was an option to choose "Auto" for GSM/UMTS band under the phone testing menu (open Phone, dial *#*#4636#*#*, click Phone Info). Auto lets the phone pick up frequencies that are not specified in the other 2 choices: USA and Europe, such as 1700 MHz and 2100 MHz.
If Europe or USA is chosen for the GSM/UMTS band, there is no way to go back to Auto and the phone is locked out of connecting to networks running on the 1700 and 2100 MHz frequencies, such as Wind Mobile in Canada and other AWS providers. This is urgent and the only way to fix it was to flash back to stock, choose Auto, and reflash later versions. Changing ROMs or modems did not work.
Does anyone else have a similar issue (you can check whether or not you have the Auto option in the testing menu) or is there a way to fix this that I'm oblivious to? I've raised a JIRA to Cyanogenmod.
Hello,
My LG G2 D800 AT&T suddenly stopped working with 4G LTE, I am from Venezuela with a service plan with Movistar and I already had my sim card ready to work with 4G also had a data service for LTE, in fact I was working with 4G for aproximately 3 months under Band 4(1700/2100) but one day without installing any additional software the phone stopped working with 4G.
I placed the sim card into a different phone and the 4G worked on that phone.
I have tried factory restore without any third part application, also included the company APN and it is still in 3G not in 4G.
I entered into the hidden menu and selected the BAND4, my android version is 4.4.2 but it doesn´t allow to select 2G/3G/4G or select any prefered network you can just search for available networks and if I do I just find WCDMA and GSM not LTE. The other option available beside Search for available networks is Automatic Selection which usually selects the LTE network but now just select WCDMA.
I also tried entering *#*#4636#*#* and try to select any prefered band but that option is not even listed, I think is the stock rom.
I don´t know what to do now, I have tried everything but I don´t know if I have to install a custom rom in order to get the option to select the prefered network. I would like to keep my stock rom because I use quick remote and some other application I know I won´t find in a custom rom.
I hope somebody can help me because the LTE data service are really expensive and I am not using right now.
Please I need your help!!
