What kind of a sim card is required for sim800 module?

The SIM interface complies with the GSM Phase 1 specification and the new GSM Phase 2+ specification for FAST 64 kbps SIM card. Both 1.8V and 3.0V SIM card are supported. The SIM interface is powered from an internal regulator in the module.

For more details see here and here. And remember "Google is your friend".

  • so if I were to go to a store to look for a sim card for a project related to sim800, I would ask for a 1.8V or 3.0V sim that complies with GSM phase 1 or 2+ specification right?

  • Actually I think it works like this; the SIM card gives a set of numbers to identify the unit when connecting to the network. The SIM800 can only connect with GSM (2G) so the SIM card must be for a vendor (service provider) that supports that. Commented Feb 2, 2016 at 13:33
  • So what kind of a sim should I ask the seller for?

  • You are still missing some info to be able to answer that. What size is the SIM card holder? You will have to ask for a 2G (GSM) SIM with the right size. Check other restrictions such as security (PIN) etc in the SIM800 documentation. It is all a question of reading. Commented Feb 2, 2016 at 13:38
