I'm looking for an unlimited mobile data plan for 3 users.

So far the best plan I can find is Unifi Air, unlimited data with no FUP, speed up to 20Mbps, RM79/month, no contract.

I need to share the internet to 3 users, what is the best way to do it?

Option 1: Insert the sim card to my phone, and use my phone as a wifi hotspot, the downside is my phone's battery will kaput quickly.

Option 2: Insert the sim card into a 4G wireless router/pocket wifi, but I'm not sure if this will work, some say I need to buy a router with modded firmware?

We need hotspot for our laptop and smart TV.

The problem is all fibre internet comes with 24 months contact, we only need the broadband for less than 12 months.
