What if China Unicom card can't receive SMS abroad?

If international roaming and roaming in Hong Kong, Macao and Taiwan have been enabled, but the SMS function cannot be used during international roaming and roaming in Hong Kong, Macao and Taiwan, there may be the following reasons:

1, some countries or regions have different network standards and frequency bands, so it is necessary to replace appropriate mobile terminals to use the international roaming function;

2. The mobile phone is set to automatically select the network, and no operator can be found to cooperate with our company. You can manually select a network by changing the setting to "Select Network Manually";

If the above problems cannot be solved, you can call the international roaming, Hong Kong, Macao and Taiwan roaming customer service hotline 8618618610010 for free service feedback (free only when you call with our mobile phone).
