The ER701-5G-OUTDOOR gateway will always try and connect to the nearest cell tower which can cause performance issues.

A lot of times the nearest cell tower is not the optimal one for LTE/5G connections, due to heavy congestion which can make the connection unusable. Having the ability to lock the ER701 to a specific cell on a cell tower that doesn't get so badly congested would improve performance.

As an example, there are 2x 3UK cell towers within 2KM of my location. One is badly congested and only provides around 35Mbps when connected to 5G NSA (B1, B3, B32, N78 (100Mhz & N78 30Mhz). The other cell tower, which is a little further away, provides 800Mbps(+) using the same band combination. The ER701 will always connect to the badly congested cell tower, because it is nearer.

I believe other TP-Link LTE products have 4G cell locking available already, it would be a great feature to add to the ER701.
