Overall very favorably impressed by US Mobile. I initially signed up for the Unlimited Starter plan. The data speeds were outstanding (Verizon 5G infrastructure) as was the reliability. So much so that I no longer need my Xfinity ISP. I decided to upgrade to Unlimited Premium after a few months. The CSR who helped me (Saad Ahmed - he gave me permission to use his name), went above and beyond to help me upgrade my plan and provide full credit for what I had already purchased. No more data cap anxiety. Another positive is fairly short wait times to talk to a live agent (< 3 minutes) and the first-level CSRs were quite knowledgeable in both instances I called and were able to quickly and competently handle my inquiries. I've dealt with numerous mobile carriers (big and small) over the years and US Mobile was first rate. Two thumbs up!
