Hello there
EC25 supports dual SIM cards, but two cards cannot be used at the same time. Only one card can be used at the same time.

Hi Duncan,
How can i use ec25 in dual sim mode?
is there need to upgrade firmware of module ?
is it possible to change EC200A or EC200T or EC25 to dual sim by firmware upgrade like EC200U?

Are there two IMEI’s if there is dual SIM support?
