Who is it suitable for and how to use it?

This small mobile phone is perfect for people who need a simple backup phone, travelers with dual SIM cards, or those who want a discreet device for recording conversations.

Buyer questions

Question: Can the phone record conversations without a memory card?
No, the phone's internal memory is limited, so a Micro SD memory card is required for automatic call recording, which can be expanded up to 16GB.

Question: Does the phone come with a SIM card, and how do I charge it for the first time?
The SIM card is not included in the package and must be purchased separately. Before using the phone, it needs to be charged for 3-5 hours using a 5V1A charger.

Question: Will this phone work in all countries?
No, not everywhere, because some countries, such as South Korea, Singapore, Japan, Australia, and Israel, have already disabled 2G GSM networks, so the phone will not work there.
