My experience with the new T-Mobile Home Internet (NOK5G21)

My first install was 10/21/2021 - TMobile Nokia 5G21 Gateway in Newark, CA.  Why - SAVINGS

Former Comcast - $ 107 month  with monthly rental.  (hardwired connection)

CURRENT LIMITATIONS:

1). Latency/Ping  - This Is My Biggest Issue - should be less than 25ms - In my cases I'm off the charts and can not use on of my VoIP services. See chart below.

Additionally, I live in a high aircraft  traffice area which gets priority.  This was an issue with Comcast too.   

Federal Aviation Adminstation - Air Route Traffice Control Center 1.3 miles

• Oakland International Airport, 19 Miles
• San Jose International Airport,  26 Miles
• San Francisco International Airport,  30 Miles

Priority to interphone transmissions puts internet and cell phone user at the bottom of the list.

1. First priority. Emergency messages including essential information on aircraft accidents or suspected accidents. After an actual emergency has passed, give a lower priority to messages relating to that accident.
2. Second priority. Clearances and control instructions.
3. Third priority. Movement and control messages using the following order of preference when possible:

                     - Progress reports.

                   -  Departure or arrival reports.

                    -  Flight plans.

4. Fourth priority. Movement messages on VFR aircraft.

2) No Port Forwarding - I required 5060:5070 UPD for my systems that currently works sporadically.

3) No option to disable "SIP ALG". This setting could be interfering withmy service (though it is intended to be helpful) and can cause issues such as dropped calls, static, echo, one-way audio (the other caller can't hear you but you can hear them and vice versa), etc.  

No Lowering the internal firewall on your router/modem.

Due to the limitations I added my own ASUS router; however, I'm still have issue so I 'm not sure how long I can suspprt the Tmobile Home Internet service. The new Arcadyan modem  still needs a firmware update to address some of the setting issues.
