US mobile is the most transparent, flexible and clear network operator I have used. Their online dashboard is extremely intuitive and you can customize your plan as per your need and budget. The network performance overall is good but I did face some issues with calls and SMSs not being received in the Philadelphia (University City) region, therefore had to port out. What makes US Mobile stand out among the sea of MVNOs is that their online customer support is absolutely top notch, never did I face any issue with my queries not being resolved. All of the support people were extremely courteous and helpful and resolved any issues as quickly as possible. When the time came to port out I really appreciated the smooth process. I received the port out information within minutes of contacting the customer support online, the person assisting, Haroon S. was extremely professional and understanding. I have seen many people from different MVNOs struggling to get the port out information, in that sense US Mobile services are highly commendable. Thank you Haroon and US Mobile!
