core: Sensors for Huawei B535-232 stops working after about 5 minutes

Home Assistant release with the issue:

Last working Home Assistant release (if known):

Operating environment (Hass.io/Docker/Windows/etc.):

Integration:

Description of problem: After about 5 minutes, the sensors stops updating and the send-sms stops working. Logs show that it is because the home assistant clients gets deauthenticated. This might be because session tokens expire faster on the B535-232 than on other models?

Additional information: The 535-232 is not officially supported by the python huawei-lte-api. The API has been tested and found working with the exception of send-sms. There is already a pull request to also make that work for the B535-232: https://github.com/Salamek/huawei-lte-api/pull/54
