Do you have a calling card specially designed for traveling abroad?

1, yes. You can go to the business halls of China Mobile and China Unicom for consultation. The card is commonly used in many countries, providing voice translation service, emergency contact service desk, multilingual and mother tongue consulting service. But you need to buy a special phone recharge card, which is more expensive, but you can continue to use it on your mobile phone after returning home.

Under normal circumstances, you can use your mobile phone to open international roaming the day before going abroad. The method is as follows:

1) Dial the service number of the operator (such as China Mobile 10086) and select the manual service. Tell each other which countries you are going to, and they will start roaming for you immediately.

2) The premise of opening international roaming is that the card has stored value above 200 yuan. If the balance is insufficient, recharge it to 200 yuan first.

3) Remember to tell the voice operator at the service desk to help him turn off the data service function. Because foreign data traffic costs are much more expensive than domestic ones, and many of them are not capped. You can't use your own domestic traffic package abroad.

3. If you go out for a long time, you can buy the other party's mobile phone communication card after going abroad, and the price is cheaper than roaming. In addition, hotels, restaurants and other places in many countries provide free wifi networks, and even if data services are not available, you can basically maintain network communication with friends and relatives every day.
