Environment:
Pam using a Samsung Galaxy SIII, stock rom, rooted, but without the latest patch.
James using a Samsung Galaxy SIII, CM10 rom, using cm-10-20121118-NIGHTLY
Solution for Pam's phone:
- dial ##DATA#
- select Edit
- enter MSL (obtain from ting, or go to the website, find Account, Device Settings, Select the phone number, and the MSL is under it)
- select Others
- select MMSC URL
- change from http://mms.sprintpcs.com to http://mms.plspictures.com
- save and reboot
Solution for James's phone:
- It seems there was no obvious way to natively edit the MMS setting with CM10. Various sources indicated I needed to edit a file. To make things easier, I installed DropBear SSH server.
https://play.google.com/store/apps/details?id=me.shkschneider.dropbearserver - SSH in, then remount the file system:
- root@android:/ # cd /system/etc
- root@android:/system/etc # mount -o rw,remount /system
- Using vi, I altered /system/etc/apns-conf.xml to replace references for mms.sprintpcs.com to be mms.plspictures.com
- Rebooted, MMS now works. Reboot may not have been necessary even.
