How to deal with overseas traffic cost-effectively

In this case, you can purchase a local data card, use a Wi-Fi sharer, and activate the international roaming function.

1. Purchase local traffic cards: There are sales points of local operators in the airport or train station, and you can purchase traffic cards of the corresponding country.

2. Use a Wi-Fi sharer: After purchasing a certain amount of traffic, the Wi-Fi sharer distributes the traffic to multiple devices through the cellular network, thus solving the problem of multiple devices surfing the Internet at the same time.

3. Activate the international roaming function: For short-term tourists, if the destination country does not limit roaming fees, it is a convenient and trouble-free option to directly use a domestic mobile phone card to roam and surf the Internet at the destination.
