HL8548-G generic samsung/iphone IMEI 004999010640000


#1

Hi guys!
I have bought 4pcs of HL8548-G module from China market
All are ok, I can upgrade the module to new firmware (5.5.24.2), can use all function
But when I want to change the IMEI to our registered IMEI serial , it doesn’t work
Below is the at command flow:
at+wimei?
+WIMEI: 004999010640000
OK

AT+KSREP=1
OK
+SIM: 0
+KSUP: 2

at+wimei=354610060035829
ERROR

at+wimei?
+WIMEI: 004999010640000
OK

at+wimei=354610060035829
ERROR

at+wimei=35461006003582
ERROR

at+wimei?
+WIMEI: 004999010640000
They all have a common IMEI 004999010640000, when do a searching on google, I found out that there is a lot of phone have this imei. I read out the AT command of the HL series and know that the module’s IMEI can be changed once. Did the seller have changed them?
Any thing can help pls let me know in this topic

Thanks for your time

@rydernguyen0101,

With regards writing an IMEI to the unit, if you have ordered a unit from Sierra Wireless with the default IMEI number of 012345678901237 then you are able to write a new IMEI number to the device once. If the unit has an IMEI number that is not the default then one of three things could have happened.

  • It was originally ordered with a default IMEI number and this has since been overwritten meaning you cannot write a new one.
  • It was ordered with a Sierra IMEI number, meaning that you cannot write it anyway, but given the devices you have bought all have the same number this is unlikely.
  • They are counterfeit and have the same number to hide this fact which again is unlikely because they power up and work.

If you are using one of our official channels then you will be able to trace the units and what they were originally ordered as using the serial number (at+kgsn=3).

Regards

Matt
