Telecom's mobile phone is taken abroad, can the information sent at home be received?

Telecom's mobile phone is taken abroad, and messages sent at home can be received. Before use, you need to apply for Tianyi International Card, and put the UIM card with dual-mode function into G-network mobile phone or dual-mode mobile phone (for international roaming and international long distance) before you can use the services provided by GSM network in G-network roaming countries and regions.

When roaming networks have different frequency requirements for mobile terminals, such as GSM/KOOC-0/900/CDMA/KOOC-0/900/WCDMA, users need to replace the corresponding mobile phones supporting GSM/KOOC-0/900/CDMA/KOOC-0/900/WCDMA. For details of international roaming services and charges, please consult the local telephone number 10000. If you need to check the account and pay the phone bill, please log in to the telecom online business hall.
