F5122: LTE with 2nd SIM not supported?
asked 2020-06-08 16:31:04 +0300
Hello,
on my F5122 (Xperia X dual sim), I can't use LTE nor UMTS with the SIM inserted in 2nd slot. Only GSM (2G) connections are established. If I swap the same SIM with the 1st slot (same SIM, same geographic location), LTE (4G) is working perfectly. After returning to 2nd slot, mobiel connection is limited to 2G (GSM) again.
Can anybody confirm that LTE works for a SIM in the 2nd slot?
Are you testing the phone with one single SIM or two? Do you have "prefer 4G" in network mode enabled for both SIMs?
