What is SIM lock?
This is a system that restricts the use of SIM cards other than those of the mobile phone company you have a contract with.
- There are two types of smartphones: SIM-free smartphones, which can be used with any SIM company, and SIM-locked smartphones, which are locked so that they can only be used with the SIM company from which they were purchased.
- If you want to use a SIM card from another company on a locked smartphone, you will need to go through the "SIM unlock" process with the company you purchased the smartphone from.
Can I transfer my SNS data?
You can continue to use social media such as Instagram, Twitter, and LINE!
