I have a XA2 dual SIM with Dutch and German SIM cards. When I insert both cards, I can not call with the Dutch SIM “geen netwerkdekking” (no coverage?). It used to work fine, but stopped working somewhere last year.
Both cards work fine in both slots when I insert only one of them. So it doesn’t seem to be a hardware problem. I also tried switching SIM 1 and 2, but to no avail. For what it’s worth, after restarting the phone and unlocking both SIMs, they both light up for a couple of seconds until the Dutch one greys out…
Thanks Tomic. I’m not sure I understand what you mean. After restarting the phone I unlocked both SIM cards with their respective PIN codes, without problems…
Update: after trying the same thing over and over again (taking the SIM cards in and out and restarting), suddenly they both worked yesterday. Then the phone shut down and now it’s the same issue again. Could it be a hardware problem after all?
