Why can't the new calling card search for a signal in Macau?

If you have enabled the roaming function of international, Hong Kong, Macao and Taiwan, but you can't use this function when roaming internationally, 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 still cannot be solved, you can call the international, Hong Kong, Macao and Taiwan roaming customer service hotline+8618610010 for free service feedback (free only when you call with our mobile phone).

If you mean that the mobile phone has no signal, it does not rule out that the signal will be affected by various factors such as topography, landforms and tall buildings. When you are in a relatively closed place, the signal will be affected. The treatment method is as follows:

1. Shut down again and try again;

2. Replace the mobile phone card with the mobile phone of family or friends and try again;

3. See if there are any signals from other Unicom users around;

If there is no signal, you can contact manual customer service for feedback.
