Your problem same with my phone.. You try type *#06# your IMEI no will appear on your screen.. I believe..your screen will appear ( invalid ) that's why your phone can't call in and out..this is your h.phone problem..not your sim.. You can put your IMEI no back and make a call in out normally.. Follow this step to put IMEI on your phone.. Take your IMEI no at the battery area normally, or get it from your HP box...if your hp have a 2 sim you must be a 2 IMEI no..copy that and follow this step..
1) type *#*#3646633#*#*
2) choose Connectivity
3) choose CDS Information
4) choose Radio Information
5) choose phone 1
6) you can see AT+ on your screen.. Just add E and your screen will appear AT+EGMR=1,7,""
7) put your IMEI no between "" for example :
( AT+EGMR=1,7,"123456789" )
😎 don't forget you must modified a little bit things, just put
the "space" between AT+ for example :
( AT *put space here* +EGMR=1,7,"123456789" )
9) and push button SEND AT COMMAND
10) on your bottom screen will appear
(AT command is mSent) in 3-4 second.
11) if your HP have a 2 simcard you must have a 2 IMEI no
12) to put second IMEI no just follow step 5 and choose
"Phone 2" after finished setup 1st IMEI at the same time
13) follow step 6 and choose ( AT+EGMR=1,10,"" ) and follow
the step until step 10.
14) after finish the setup just restart your HP
15) after restart type *#06# and your IMEI no will appear,
and your phone will be OK. If not working send your HP
to your hp service centre..TQ..GOOD LUCK.
Try dialing *#31#.....i dunno this might work?
