I have a Nokia gateway and I have seen several for sale on eBay for $100 or less. I may be wrong but I believe you just move the Sim card to the new device. This would allow one to add external antennas and make changes without worrying about damaging their box. Let me know what you think and if T-Mobile would even allow you to do that.
What is the latest software version for the Nokia 5G21? Mine is running 0313. Thank You
