Hey, make sure you've entered the details correctly. Have you texted "Settings" to 2020?
Here are the MMS settings you'll need to have installed on your phone, so maybe browse through your settings and double check:
Connection Name: giffgaff - MMS
APN - Access Point Name: giffgaff.com
MMS proxy: 126.96.36.199
MMS port: 8080
APN type: mms
Thanks so much for helping guys, I know I must be frustrating the life outta you. I've checked all that and it seems ok but the mms still isnt sending and when I go into details it says Network Error: Try again later. Sorry, think I'll just give up lol xx
Sounds like the classic symptom of not getting you APN settings changed. Changing these settings allow you to access the mobile internet and send/receive MMS.
