Hi, I have an xa2 plus with Bouygues as operator and I don’t have any problem on 4.3. (exept with mms)
Did you try to reboot your phone or switch to airplan mode?

#3

Please try switching from dual to ip (settings / mobile network / data access point) and tell us, if this changes anything.
Cheers

Sorry to reply with a delay.
@kayoux I made several reboots and also tried to switch to airplane mode as usual. Nothing changed.
@tobset I already tried this (I already had this kind of problem with MMS, so I check it anytime a new update is done)

I had to flash my phone to get it useable. I’ll give a new try this afternoon.

Hi @kuronoyurei ,
My conf is :
Nom du point d’accès : a2bouygtel.com
Protocole : IPv6
Authentification : aucun

#6

Thanks a lot, it was that IPv6 protocol change.
Before the update, it couldn’t work without mixed protocol. Changed for IPv6, and everything seems fine for now.

#7

In addition, I had to change my settings for MMS, see this post

#8

I had the same issue after 4.3.0.12 update. I changed the Data Access Point Parameters to:
Connexion name : Bouygues
Name of the access point : mmsbouyguestel.com
Protocol : IP
Authentication : None.

Everything is working OK after changing parameters of the data access point
