Frequently Asked Questions (FAQs)

1. Is there a mini SIM card?

All GSM-based phones use the same size of chip, but the plastic frame around it, comes in 3 different sizes: Mini SIM (= 2FF): 25 x 15 mm. This used to be the standard for many years from 1996 and still is the most common size around.

2. What is a mini SIM card?

Mini-SIM (2FF) SIM cards were introduced in 1996 and have the same contact arrangement as the full-size (1FF) SIM card. The 2FF 'mini-SIM' is distinctly smaller in size than the Full-size SIM with dimensions of 25.00 mm × 15.00 mm × 0.76 mm. Some networks refer to the 2FF mini-SIM as the Standard SIM or Regular SIM.

3. What SIM card type has smallest size?

The smallest SIM card available is the Nano-SIM format, which measures 12.3 × 8.8 × 0.67 mm. Most current mobile phones and mobile devices use a Nano-SIM slot.

4. Can I use mini SIM in normal phone?

The mechanics of using a nano SIM in a non-nano phone are simple enough. First choose the appropriate adapter – in this case the nano to micro one – pop in your SIM card and then pop the SIM/adapter combo in the card slot. There's another issue to think about though, and that's the network lock.
