MAX OTG network type and sms

HI guys!

I would like to request the following:

1.) when using huawei E3276, i hope we will be able to select which network type (3G only, 2G & 3G, LTE only, 3G and 4G only, 2G / 3G / & 4G, etc.)

2.) If we can incorporate SMS function it would be great, like receiving commands via sms, or manually using MOTG to send sms to register data services (as we sometimes use prepaid data sims)
