For a while now my I8150 doesn't allow me to make any outgoing calls or connect to 2 or 3G- when trying to make a call, it says 'ACM limit exceeded'. outgoing/incoming SMS is fine, and I can receive calls without any problems. WiFi works fine.
I've searched for others facing similar problems with other Samsung phones, but all point to a faulty sim card; the same sim card works flawlessly on other phones.
I'm running CM9 unofficial but tried many different ROMs to no avail... clean installed each time I changed ROMs but that doesn't seem to make a difference.
Anyone have an idea what it could be?
