Huawei How to enable or disable roaming

If the Huawei device is connecting to a foreign or unknown network, there will be no data packet sent unless roaming is turned on. Only if roaming is activated, you can use the mobile data network of a foreign country, this can (and mostly will) lead to additional costs.

Note: In european countries you can use EU-Roaming and use your internet as if you were at home. We still recommend to talk to your carrier first.
