Is it okay to send text messages to friends and relatives by overseas phone?

Yes, it is ok to send short messages to friends and relatives from overseas, but there are some problems that need attention. First of all, you need to enable roaming function, so that you can send and receive short messages normally abroad. Secondly, you need to pay attention to the cost of SMS. The cost of overseas SMS is usually high, so you need to use it carefully according to your own phone bill. In addition, if the mobile phones of relatives and friends do not have the function of international roaming, or are in special circumstances such as flight mode, they may not be able to send SMS successfully. Generally speaking, it is feasible to send short messages to overseas relatives and friends as long as you pay attention to relevant matters.
