S7 from Sprint has limited to no connectivity

metrolevelone

    I have recently moved my unlocked S7 from Sprint to T-Mobile.  I am constantly losing network access, and have had to toggle Airplane Mode on/off to get a signal back.   In some places, I have zero bars.

     

    I was able to get a demo device to verify if it's my location that's causing the issue.  The coverage map shows I should have full connectivity.  Well, when I had the S9 from T-Mobile, I had full bars and no dropped network connectivity.

     

    Is there anything I can do to keep my S7, and have the strong network?  Why would the device matter?
