Network Connection Problem in Dallas Area in May 2018


    I live in New Mexico and come to Dallas area to visit.  From the time the plan landed in Dallas on 5/11/2018, my phone cannot make connections to T-Mobile networks.  I have called T-Mobile and visited their stores but the problem has not been resolved.  My relatives are on the same service plan and having the same brand phone; they do not have the problem.  Help.
