Dear Customer, we have over 10 years experience dealing with inbound/outbound SMS, managing it on enterprise level. We use GSM Modems, Android Modems, SMPP Goip, and many other solutions. We ask that you look no further and hire us. We won't disappoint you because we've got the right experience in this field. Let us chat to discuss this further. Based on discussions, I adjusted my BID. I will give you a portable android based app, and web based interface on your stations, to enjoy sending receving messages using GSM SIM card installed in androids. I require android 4.2.2 using any cheap phone used is ok. If you send 1000's of messages maybe we need to root your device so that android does not think someone is flushing your prepaid bill.
