Designed for Boosted internet 4G internet wherever you are.   Unable to connect to a sites shared Wifi?  Looking for a boosted 4G signal where your phone may sometimes struggle?  Going camping and want boosted internet in your tent? using your vehicle as a mobile office?   Maybe you are looking for an internet solution that isn’t permanently fixed to your van and gives you the freedom to use wherever you wish?  The  Falcon 4G DIY internet system gives you the freedom to do all these things and get online without having to rely on campsite WiFi, providing up to 2.5 times the 3G or 4G performance of your mobile phone thanks to the high performance antenna.

The suction mounted window antenna uses MiMo (Multiple input, Multiple output) technology to send and receive more than one data signal simultaneously for the best possible 4G speeds.

The included MiFi hotspot connects to the 4G/3G network via the roof mounted antenna and provides a WiFi hotspot for you to connect all your devices to (up to 10 devices at once).

The LCD screen on the front displays the network name and password as well as important information about the connection including the current speed, data used and the number of devices connected via WiFi.

For most users all you will need to do is switch it on and connect to the WiFi network using the password shown on the display but for more advanced users you can access extra settings via a web browser or by using the free app available from the Apple App Store, Google Play store on Android or the Amazon store.

The MiFi unit also has its own internal battery which lasts for 6 hours so you can unplug it from the charging mount and take it with you for portable use although the performance will be much less than when used with the roof mount antenna.

The system works on all UK and EU frequencies for 4G LTE at speeds up to 150Mbps and is backwards compatible with 3G up to 42Mbps and even 2G networks where supported. It is completely unlocked so will work on any network giving you the freedom to choose your data network service provider.

German Manual: German 4G DIY User Manual



SIM Card: You can use a SIM on any network but we include a Three SIM card which gives you 200MB of free data a month once you have registered and you can then top up with packages of your choice.

Travelling Abroad: Three offer “Go Roam in Europe” on all their plans which covers roaming in 49 European destinations and “Go Roam Around the World” which covers 71 destinations worldwide. If you have a data plan of 12GB or more you can use up to 12GB when roaming in other countries at no extra cost.
In “Go Roam in Europe” destinations data use over this limit incurs a surcharge of up to 0.50p/MB. In “Go Roam Around the World” destinations data use over this limit is not allowed.

For “Go Roam in Europe” Three say they may charge a small surcharge if you spend the majority of your time abroad and use more data abroad than you do in the UK over a rolling 4 month period. The enforcement on this seems to vary a lot but should it happen you will be notified beforehand. If you roam exclusively in a “Go Roam Around the World” destination for any 2 complete months in a rolling 12 month period, Three say they may suspend international roaming on your account.
Most of our customers don’t find these these restrictions to be a problem but if they are it is possible to order additional sims as a backup and of course you are free to use any SIM and any network of your choosing.

For more details on Three’s Go Roam service and the countries covered please see the Three website.

If you are travelling abroad please read the instructions on how to enable roaming on your device before leaving the UK.

    Needed better internet connection on my van. FItted a Falcon 4G system, the great kit got unlimited data which is great for streaming and browsing. In Devon phone signal can be weak but this is getting full bars of 4G. Great product

  2. Peter Watson

    We like to go camping but missed having internet, Using our smart phone does not always work when signal is poor. We purchased this product from Falcon when they were at the NEC in 2019 before lockdown and have had now for 2 years works great. Delivers strong signal & pug and play. Had a slight problem when swapping a sim card to a new provider but soon fixed by the support team with the advice how to change the settings. Great product and great services
