How to solve the problem that the newly bought Apple 4S mobile phone can only receive short messages but not send them? The mobile card is what I always use.

Apple's 4S mobile phone does not support mobile network, so it can't be used. At present, Apple's mobile phone 4s doesn't have a mobile 3G version, so it can't use a mobile card. It depends on the mobile phone network standard, which determines the network used by the mobile phone.

Apple's 4S mobile phone formats are GSM, WCDMA, CDMA and CDMA2000, so it supports Unicom 3G and Telecom 3G, but does not support mobile 3G.

Mobile 3G network standard:

Network standard: TD-SCDMA(3G), frequency bands 1880MHz- 1900MHz and 20 10MHz-2025MHz.
