1. GSM Phone nga mu connect to 900MHz only
2. Any device, gsm modules, nga pwede mu connect to 900MHz only, send text/call or anything
2. How to manually connect to 900MHz only
3. Legit document/PDF/reference about philippine telco frequency assignments sa 2G/GSM.... kbw ko unsa but i need a legit reference to cite (for educational purposes)
4. Last resort, a GSM 1800MHz JAMMER para mapugos ug connect to 900MHz ang phone/network

Salamat daan. This is for educational purposes and maybe in time if successful ang amoang intention we can share it here.
