Looking to open a cellphone store? Opening a phone store takes a little knowledge upfront on what carrier you should sell, where should your location be, and should you sell online?
Some of the best prepaid carriers in the US are H2O Wireless, Page Plus, Boost Mobile, Virgin Mobile, Solavei Wireless, Simple Mobile, and there are many more wireless carriers out there.
Every company I know of other than Solavei requires a payment system in place to get the bulk of the commission you will need to operate on. Solavei Prepaid Wireless pays you month after month and the customers can pay their bill online.
