I go to the internet cafe to turn on my phone, and after scanning my ID card, I will send a short message verification code to my mobile phone, but I have already set up two mobile phone cards with my ID card. Which mobile phone will he send it to? It depends on whether there are internet cafes that are often used here or which communication company has handled the short message sending business.

For example, if it handles business with China Mobile or China Unicom, it will probably send short messages through China Mobile or China Unicom.

In most cases, it will be handled with the three major operators, and there will be a priority order.
