I am using Arduino GSM Shield (integrated antenna - A000043) for my project. The shield uses a radio modem M10 by Quectel. The M10 is a Quad-band GSM/GPRS modem that works at frequencies GSM850MHz, GSM900MHz, DCS1800MHz and PCS1900MHz.
I will really appreciate if someone can tell me that what carrier SIM card is compatible with this GSM module for Arduino. I live in Toronto, Ontario, Canada.
Thank you
