China Mobile can't find the data in Dubai.

Yes, China Mobile's data signal in Dubai may be weak or unable to cover the area, so you can't use mobile data normally. This may be because the operators have not built base stations or data transmission facilities in this area, or because the local telecommunications policy has restricted the operation of China Mobile in this area.

If you need to use mobile data in Dubai, consider the following solutions:

1. Renting a local SIM card: Renting a local operator's SIM card in Dubai is a common solution. These SIM cards usually contain a certain number of minutes and data traffic, which can meet your basic communication needs during your stay in Dubai.

2. Use international roaming package: China Mobile provides international roaming package, which can be activated when going to Dubai. These packages usually include data traffic and other communication services for a specific period of time. Specific tariffs and preferential terms can be found on China Mobile official website.

3. Connect to WiFi: If there is a WiFi network available in Dubai, consider using the WiFi function of the mobile device to connect to the network. This may require you to buy a WiFi package in China Mobile official website or use a local public WiFi hotspot.

In short, if China Mobile's mobile data cannot be used in Dubai, you can consider the above solutions to meet your communication needs. It should be noted that international roaming packages and WiFi connections may generate additional fees, so it is best to know the relevant fees and usage rules before using them.
