They are included in Android. The correct settings are determined by your SIM MCC and MNC (Mobile Country Code and Mobile Network Code). If you want, you can view the list of preset APNs by looking at the source code, for example at android-source-browsing. The file name in this case is /etc/apns-full-conf.xml, but apparently it varies.

Yes, just copy the /system/etc/apns-conf.xml file. You can also use an app like APN Backup & Restore: https://market.android.com/details?id=com.riteshsahu.APNBackupRestore Edit: To backup manually-entered APNs (or ones otherwise not part of your ROM, such as ones "imported" when you insert a new SIM card) you also need to back up ...

APN settings are necessary for data service on GSM and related networks (UMTS, LTE) to work. It defines what network to connect to and the configuration of the network (e.g. the gateway GPRS support node address, which is the interface between the mobile network and the public internet). APN settings are always required for data service on GSM and related ...

Next to the pre-configured settings from /etc/apns-full-conf.xml as described in onik's answer, some providers offer to send you so-called "service SMS" for an automated configuration. Opinions on those are quite confusing: Some say those do not work on Android or iOS devices, and you'd have to enter APN data manually (e.g. Simyo in Germany), while others ...

I have been told by Verizon that it's a bug on the Samsung Note 2 and S3 after Jelly bean. Verizon / Samsung are working on a fix so you can modify the APN in near future. Verizon didn't intend a deliberate prevention on their part (confirmed by the fact Verizon HTC Droid Incredible 2 running android DOES allow you to modify the APN and works perfectly for ...

I am from the USA and have the Verizon S3 with Jelly Bean. I am currently in the UK. Used my usual UK VodaFone Sim card and it immediately worked for both Voice and Texts (something it didn't do when I was here in November before the Jelly Bean Update). The reason it won't work at all in SOME countries is actually SIMPLY (but major) because Verizon seem to ...

I just found the phone specs on MTS India, and seems like the second SIM supports only 2G voice + SMS, not data. This is because the phone is Dual SIM Dual Standby (DSDS), not Dual SIM Dual Active (DSDA or DSA), and there isn't a 3G GSM radio. DSDS means that if you have a data connection or a call open, the other SIM is disabled. This would prevent the use ...

A family member also has the same device, and also uses hangouts, so I was able to copy the APN information from him. For any future reference, I got MMS to work again by adding these recods to the Google Hangouts APN List. Name: LTE - Verizon CBS MMSC: http://mms.vtext.com/servlets/mms MMS Proxy: not set MMS Port: not set MCC: 311 MNC: 480 ...

Aha! Ok I'm no where near a cellular expert but based on a wild guess I searched for carrier APNs and found here a list of APNs per carrier per country. I guess these are always required but somehow cyanogenmod is not configured to determine these codes automatically. While this may help others facing the same problem, I hope someone with real insight ...

The APN (Access Point Name) is generally the gateway between your providers 3G network and the Internet. They are usually auto-detected but occasionally you have to enter them manually when you swap providers.

It seems that the save option for APN is not active on android 4.1.1 (at least when you have zero APN previously stored. But after creating a new APN and filling parameters, if you shut down completely the device, (and do not try to activate save option through the button, act that would erase all parameters introduced), it will be saved somewhere. You will ...

I am having this problem too after inserting local SIM. Calls and texts are OK, I need to configure an APN for internet. A Verizon Global Support Technician told me that it is beyond Verizon's control to add an APN and that Samsung will need to provide directions on how to do this. I got online to chat with Samsung and the guy told me he can't help me on ...

APNDroid doesn't work on CDMA phones. This appears to be the case with most such apps. Internet Scheduler and GreenPower claim to work on them if you have Gingerbread, though. There are some other solutions you can try in this Google Groups thread.

Did you try adding the messaging settings to the APN you created? You can add both webs as mms settings and then select that APN.

Also see http://forum.xda-developers.com/showthread.php?t=734138 for a discussion about how they might. Mechanisms other than APN change might include Time to live Request header Data volume Answer seems to be probably not.

I really like APNdroid and haven't had problems with it at all. However, I've got an HTC Dream that's unlocked and running on AT&T so it is pretty much guaranteed that I'm not getting OTA updates. You can always access your APN settings directly, so even if an update broke your APN settings, you should have been able to go in through Settings > ...
