move Home Internet SIM to personal router with external antenna

I don't think that will work since the SIM is hardcoded to the device (gateway) as well as the location. I'd be surprised if you got this to work, but if you do, please let us know!

For the record, it drives me nuts that T-Mobile didn't allow for an external antenna port on the gateway. There simply isn't an easy or convenient way for those of us who would be willing to spend the money to mount an external antenna to connect it to an Arcadyan KVD21 5G gateway.

¡Buena suerte!

Easy, convenient ,,no... but yes its done everyday, just expensive way..

The SIM and Gateway are not paired.  A few months ago, I had to swap gateways.  Before shipping the old one back, I put the SIM from the new gateway into the old gateway and it worked.

You can use an unlocked phone on the network by moving your TMO SIM from a TMO phone to a non-TMO phone.  So I don't think your personal router need to be registered on TMO to be used.

At this time, I am guessing that since TMO runs on IPv6, it would have a DHCPv6 running. Is your new personal router able to request IP v6?

Also, have you called tech support?  Since the service comes with the gateway, pretty sure you are the only person to want to do this. Unless you get lucky and a TMO tech is online, asking for a solution here is futile.

It isn't so much as the SIM as it is the Gateway.  T-Mobile's Gateways are all whitelisted.  Anything that isn't, will not work with a TMHI SIM.

If you want an external antenna,  you can look on YouTube for NaterTater who has done this.  Personally,  I don't want to spend the $400 on an antenna,  and my service is good enough.

Also, TMobile reps did state that I could take the home internet device to a vacation rental.

Actually, you CAN use your t-mobile home internet SIM in a non t-mobile modem/router combo. Device blocking has nothing g to do with the SIM card and everything to do with the IMEI number of the device.

You can buy an after market modem/router combo that allows you (via firmware) to use the same IMEI number as your t-mobile modem. Just put your SIM in and you're all set. T-mobile will be none the wiser.

An added bonus is that these modems have LOTS of features such as band locking. Also antenna ports that make it easy to connect an external antenna.

As an example, check out the Cheetah Wi-Fi 6 Industrial LTE 5G NR Wireless Modem

What makes you thiink you can change routers?

@rpracing, just for fun, I tried the concept (use my T-Mobile SIM card in another non T-Mobile device) and was unsuccessful. To jump onto the T-Mobile network you need to be authenticated by T-Mobile, through your SIM card. Sorry, it won't work.  

It's not hard coded to the location, the reason I want to change routers/gateways is because the router I want to use has an external antenna which gives me better signal and the one that T-Mobile provides does not support and external antenna
