Special note on dual SIM dual standby single pass

This communication device adopts The ”dual-sim, dual-standby, single-pass” design means that if two card numbers be inserted at the same time, voice services cannot be used at the same time, and data Internet services cannot be used at the same time. When one of the card numbers is in a voice call, the other card number cannot answer the call. If there is a call from the other card number at this time, you may hear “The call you dialed is not in the service area”, “The user you dialed is temporarily unavailable, please dial again later” and other prompts that cannot be connected. The above situation is caused by the “dual SIM, dual standby, single pass” design, it has nothing to do with the operator’s network status. Single pass is because this device is designed with a single chip, which can greatly improve standby time and reduce power consumption. It is recommended that users consult their local operators to activate relevant services to avoid the problem of missed calls without reminders in the scenarios mentioned above.
