Inserted new SIM from UPC, no network service. Had to call tech support to manually enter the APNs settings.
Phone now work, very poor quality but I think this is the price to pay to be with UPC which I didn’t expected to be so poor.
Inserted SIM from Swisscom, phone works flawless.
MMS not working. MMS with Swisscom SIM works.
If I enable the APN for MMS under UPC, the service becomes unavailable.
Also I requested to be called back from a person that I spoke in the Administration, no call so far.
