* * * Enjoy SMS without service. Can the other party see it right away?

No, it won't be received until it returns to normal within 48 hours.

When the mobile phone has no service, no signal or is turned off, if the mobile phone is in a state of non-arrears, the three major operators will automatically save the SMS for 48 hours by default, and no information will be received after 48 hours.

When no signal is received, it may be that the network is busy, the mailbox is full or other hardware problems. If these factors do not exist, please contact the local manual customer service to solve the problem.
