As an update - i tried again with my 10iii after upgrading SFOS to 4.4.0.72:
One first load (after upgrade, and restrart after inserting sim) i did very briefly catch a tiny error message scrolling across the top. Said something like: “problem enabling settings from sms” or some such. Doesn’t prompt on every sim swap, so can’t immediately recall precise message.
It also received the customary text message:
“we will shortly be sending you a text with some settings.”
Which never arrives…
Checking the settings for MMS after a new load of the sim seems to lose the settings that are present (and work!), in my XA2 Plus:
Connection name = “Talkmobile MMS”
Access point name = “talkmobile.co.uk” (dropping the “pay.” prefix on working XA2 Plus)
Protocol = “Dual”
Authentication = “None” (dropping the “Pap or Chap” on working XA2 Plus)
Proxy address = “212.183.137.012” (adding a “0” into number on working XA2 Plus)
Proxy port = “8799”
MMS message centre address = “http://mms.talkmobile.co.uk/servlets/mms”
Outcome:
Regardless of replacing the settings exactly as found in my XA2 Plus, trying to register for 4G calling and restarting (as per the new .72 release), and trying all of this both sim 1 and sim 2, at no point do i get working mobile data.
Ofonologs:
Yes, i haven’t had the time to work Chum out yet, no doubt i will get there one day, hopefully usefully before SFOS 4.5 arrives but who knows…:
