I'm going to open an international telecom card for global roaming in the telecommunications bureau. If I use a telecom mobile phone, I'm going to travel to Europe and call the Internet when I travel to Europe. Telecom's mobile phones use CDMA technology, such as CDMA networks covered in the United States and other countries.

However, the network in Europe is G-network. If you use a telecom mobile phone to go to Europe, although it is claimed that you can roam internationally, you can also make a phone call, but you need to first transmit the telecom C network signal to the G network, and then use the G network to make a phone call and send a short message. The signal is unstable, and because there are many transcoding, the charge is higher than that of mobile phones, and the most abnormal thing is that mobile phones (especially G-network mobile phones) can roam only with telecom cards. Last time I went to Russia, I couldn't roam because I brought a telecom mobile phone. My colleague brought two mobile phones, one for telecom and the other for mobile. The mobile phone roams only when it has a telecom card, and the signal is super unstable.

As for the charges, if you roam around the world, you will be sent a text message every time you go to a country, telling you that the standard is at your own expense, and you will save money no matter how you call.

Anyway, I suggest that if I go to Europe, I still have an international roaming of my mobile phone number, which is definitely no problem. Telecom is hard to say!

Mobile phone calls cost 3.99 yuan/minute, and text messages cost 1.99 yuan/piece, probably. I can't remember clearly. There will be a text message coming.

When you are away from home, you should report your family's safety, contact is convenient, and you must do a good job in mobile roaming!
