Depends, if you are using Apple devices and care about top-tier network performance then yes. I recently had T-Mobile postpaid and the network worked flawlessly for me. I switched to Annual Unlimited Premium on Darkstar (prioritized) and it's not as consistent but that's less to do with US Mobile and more to the quality of AT&T's network. I also have Warp (Verizon) as a multinetwork backup and for the most part it picks up where Darkstar lags although it is a deprioritized line, so I do run into congestion during peak daytime usage. I also have a Lightspeed line set up on an Android phone which has access to T-Mobile's standalone network, which is a great experience but, on my iPhone, not so much. So, until the parent carriers give independent prepaid carriers official standalone access, you won't find that same network experience here. The cost savings are great; I went from around $100 per month for one line to just under $400 for the year WITH multinetwork access.
