Issue with RM502Q-GL never connect to internet

I order this module from Aliexpres, with Banana PI R4. then I tried both openwrt and Rooter GUI a ported 5G openwrt and none of that picking up LTE/5g Signla.

Each time I boot the system wait 2 mins then it disconnects the modem and sometimes gives error like " SIM locked No sim pin inserted" my sim has no pin lock also gives me another error which No IP address obtained !!

with all tires I did since I bought this module I never had connected to internet.

Kindly have a look to mode log.

Last thing i come up with. I thought ISP is blocking the modem imei.
I change the modem IMEI to Iphone and I change TTL to 64 with hostless option.

Now it gives me IP address but no internet, the modem keep sending check connection 7 times then restart itself.

@silvia
It didn’t work either, but I resolved this issue after upgrading my Modem version to RM502QGLAAR11A02M4G_01.200.01.200. Before, the modem only used ECM, which ended up with a lot of issues, including the modem restart and locking my SIM. Now, after the upgrade, the mode can switch between protocols easily, and it has 3 tubs.

For anyone who has a similar issue refer to this post here helped me a lothttps://eko.one.pl/forum/viewtopic.php?id=24137
