BG95-M3 Taking 30 minutes to register

Hi, We are trying to use a BG95-M3 instead of a BG96 and we have managed to get it working with the same commands, but the bg95 takes considerably longer to register to a tower than bg96, as in 30 minutes vs 2 minutes.
Here are some details:
Network: 1oT
Country: UK
Protocol: PPP
Commands sent:
I (11395) [PPPOS CLIENT]: AT COMMAND: [AT…]
I (11415) [PPPOS CLIENT]: AT RESPONSE: […OK…]
I (11515) [PPPOS CLIENT]: AT COMMAND: [AT+CFUN=4…]
I (11535) [PPPOS CLIENT]: AT RESPONSE: […OK…]
I (12305) [PPPOS CLIENT]: GSM initialization start
I (12905) [PPPOS CLIENT]: AT COMMAND: [AT…]
I (12925) [PPPOS CLIENT]: AT RESPONSE: […OK…]
I (13025) [PPPOS CLIENT]: AT COMMAND: [ATZ…]
I (13045) [PPPOS CLIENT]: AT RESPONSE: […OK…]
I (13145) [PPPOS CLIENT]: AT COMMAND: [ATE0…]
I (13165) [PPPOS CLIENT]: AT RESPONSE: [ATE0…OK…]
I (13265) [PPPOS CLIENT]: AT COMMAND: [AT+CFUN=1…]
I (13295) [PPPOS CLIENT]: AT RESPONSE: […OK…]
I (14395) [PPPOS CLIENT]: AT COMMAND: [AT+CNMI=0,0,0,0,0…]
I (14415) [PPPOS CLIENT]: AT RESPONSE: […OK…]
I (14515) [PPPOS CLIENT]: AT COMMAND: [AT+CPIN?..]
I (14535) [PPPOS CLIENT]: AT RESPONSE: […+CPIN: READY…OK…]
I (14635) [PPPOS CLIENT]: AT COMMAND: [AT+CREG?..]
I (14655) [PPPOS CLIENT]: AT BAD RESPONSE: […+CREG: 0,0…OK…]

It keeps replying with CREG 0,0 for 30 minutes until it finally responds with CREG 0,5 and connects like expected.
Again, the BG96 in the same environment, location, time, antenna, board design only needs about 2 minutes.
Is there a command that I should be sending to force it to try to register?

since bg95M3 support NB RAT, for all band scan of NB need about 30 minutes , so for the first time to register , it is ok ,

and then the registered PLMN ,will been saved in SIM card , so for the second time registrtion , it should be quick .

so pls reboot module and try again . if the registration time is long still, pls reach to support@quectel.com for more analysis

So if you change SIM card, it will take 30 minutes again?

I have noticed the first time registering taking longer than subsequent ones on the BG96, but the BG95 takes over 30 minutes every time I power it up. Is there a way to only scan for GSM bands?
