Suitable plans for LB1120 4G LTE Modem

[yanldst]

Recently, I got one 4G LTE Modem. 

I have several questions about how to choose a SIM card:

1.  Which service provider should I choose?

2. What kind of data plan should I choose? 

3. Do some providers have pure data plans?

Some more questions:

Will I get a static IP address if I keep this device always at the same place?

If some friends have the experience, please help me to solve my concerns.

Thanks!
