Free Alcatel MiFI with any 5 SIM Plans and 1 Data Plan

An Alcatel MiFi is a business mobile hotspot device giving you access to your own private WiFi network. With this device you’re able to connect up to 15 devices from one location simultaneously, giving your employees the ability to work seamlessly when out of the office.

  • Alcatel MiFi is a pocket-sized business mobile hotspot and business internet solution that’s easy to use and gives you access to your own private WiFi network.


  • Setup your own private office: You can connect up to 15 devices to a single Alcatel MiFi hotspot.


  • Connect WiFi only devices to a mobile data connection: When traveling for work being able to connect your laptop or tablet to WiFi can be a right pain. With Alcatel MiFi you create a wireless network and can get any WiFi device online.


  • No more slow hotel, train or other WiFi: Hotels and trains still charge for WiFi, even those who offer it for free don’t offer the speed you’d need to work. Get faster speeds with your own private network.


  • Use as a DR device: In case your office suffers a loss in internet the MiFi can help keep the business running.


  • Long battery life: From a single charge you can operate the MiFi for up to 6 hours and with a standby time of up to 12 days this is a great tool for your business.

* Gifts are one per customer, while stocks last. Gift promotions can be very popular and while we do our best to ensure everyone receives one, there can be instances where the gift contents may be substituted, and/or we run out & therefore are unable to fulfil the gift offer.
