Hi,
We tested our EG915U-EU modems on Vodafone Ireland and they worked perfectly with this firmware:
VERSION: EG915UEUABR02A05M08

Since updating to this version (below) we can no longer register on Vodafone Ireland unless we set the modem to 2G with AT+QCFG=“nwscanmode”,1,1. I suspect this problem is not isolated to just Vodafone Ireland. I can confirm later.
VERSION: EG915UEUABR03A01M08

When the scanmode is left to auto we get ‘LIMSRV’ on the updated modems.
Non-updated modem:
+QENG: “servingcell”,“NOCONN”,“LTE”,“FDD”,272,01,24A5249,66,9460,28,3,3,CF6E,-87,-15,-56,48,34
Updated modem:
+QENG: “servingcell”,“LIMSRV”,“LTE”,“FDD”,272,01,24A5241,4,300,1,5,5,CF6E,-111,-16,-77,46,10
We’re using the same SIM and same hardware. The AT+QCFG=“band” settings are identical.
Using this SIM in a Qualcomm EG91 gives the following results:
+QENG: “servingcell”,“NOCONN”,“LTE”,“FDD”,272,01,24A5241,4,300,1,5,5,CF6E,-101,-15,-66,-3,20
