Hi, I transferred over to ID mobile from O2 and since doing this have been unable to send text messages unless connected to Wifi. imessages are sending no problem.
The phone did not have this issue until using the ID sim, I am unable to view any APN settings so cannot check/change these manually.
ID support advised that in order for an Iphone to send text messages you need to disable imessaging which has to be the weirdest advice i have ever been given, (and for reference “ID Mobile” I have imessaging enabled on my other 2 iphones and have no problems sending text messages on Vodafone or Giffgaff).
Any suggestions to resolve this would be appreciated as this has been ongoing for 3mths now.
