Use sms man or smshub etc..

we’re looking for reliable USA non-VOIP SIM suppliers (T-Mobile, AT&T, or Verizon).
We have our own website, high traffic, and can integrate via GSM modem or API.
If you have a modem or API and are interested in earning from your SIMs, please reply so we can discuss further.
