TMONews points out that there are a number of threads on HowardForums and Reddit showing that a considerable amount of T-Mobile customers are seeing connections drops and crawling speeds.

It is not just one device having issues as people on the Nexus 5, iPhone 5, iPhone 5s and the OnePlus One have all been dealing with these network issues.

TMONews puts out a possible theory as to this recent outage:

“To me, this seems like a simple case of teething issues. Like I’ve already mentioned, there are always problems when networks are being upgraded. And you only have to read posts here from the past few weeks to know that VoLTE, 4G, and Wideband LTE are being activated in new locations at break-neck speeds. But, just to be sure that is the case, and it’s not your phone or SIM card, you can try a few things.” – TMONews

All major wireless carriers have been dealing with recent outage issues. Several weeks ago, Verizon suffered a national outage themselves which didn’t allow most customers to pay their bills and access other parts of their customer account. AT&T also been dealing with outages lasting just a few hours in several cities.
