Atm i have the mr400 but that doesnt let you choose to whicb isp you wanna connect to.

Iff it connects with tmobile i cannot say go to vodafone.

I want a 4g router with antenne like the mr400 but with isp selection options   i roam a lot so i wanna select The isp myself and get the fastest isp

Yes i know the mr400 v4 and up does have that , but when i Look at amazon i dont see the version number of the product.

Give me some options.
