tp-link 4g router does not recognize sim card
my router does not recognize my sim card.
I've tried two different ones from different cell phones.
Both cards are standard issue 4G/LTE and work just fine in a cell phone.
When inserting into my tp-link router, the software tells me "no sim card".
I've done a reset a couple of times, alas to no avail.
The question is whether the card reader is defective?
No way of knowing for sure, is there?
Or is the the nano format of my sim cards responsible?
But that should work according to the manual.
Would it make sense to just renew the firmware?
Thanks for help
