HARDWARE (XA2, Xperia 10…): Xperia XA2 - Dual SIM
UI LANGUAGE: DE
REGRESSION: (compared to previous public release: Yes, No, ?): ?
In order to check functions on Xperia 10 ii before installing SFOS i removed the second SIM from my actually used XA2 Dual -SIM. Both SIM cards are for German D1 network (GSM 900 Hz frequency). The first one Congstar (low budget provider from Telekom), the second one Telekom.
Outbound calls form Xperia 10 ii work well. On inbound calls not the Xperia 10 ii Dual - SIM rings which holds the SIM card but the old XA2 which doesn’t hold a SIM card for the called number any more!
Even better, it won’t stop ringing until i dismiss the call via touchscreen actively.
In consequence my second SIM is tied to my XA2 forever for incoming calls (Ghost SIM card)!
If i use my first SIM card (Congstar) to test the Xperia 10 ii inbound and outbound calls work fine.
Disabling the SIM on the XA2, restarting it many times, move the the first SIM to the card slot for the second SIM and restarting, leaving the XA2 device for half a day in order for the provider to update - nothing helped.
If i pick up the call to the ghost SIM card in XA2 (phone number tied SIM is not inserted there but in new phone) i can make a normal phone call.
If the XA2 is turned off and the second SIM is inserted in the new phone i get the signal indicating the line is occupied / no service.
If no SIM is inserted in XA2 device at all and i call the seconds cards number inserted to the new phone i get occupied / no service signal.
- see description
- use Xperia XA2 (multiple OS versions over time) with two german D1 SIM cards (belonging to one company and its affiliate)
- use phone in this configuration for 1 - 2 years, travel around europe
- remove second SIM and insert it to Android phone
- inbound phone calls are still received by the Xperia XA2 not containing SIM any more
Inbound calls to second SIM are routed to new phone containing the SIM card and not to the phone not containing the SIM card tied to the number.
Phone not containing SIM card any more rings on inbound calls and doesn’t stop until call is dismissed on touch screen.
