Perhaps the main selling point of the GlocalMe U3X Mobile Wi-Fi Hotspot is the way it can work with or without a SIM card – in the latter case using its own cloud SIM technology to get online.

The TP-Link M7350 is undoubtedly one of the best portable Wi-Fi hotspots you can buy at the moment, and while it can reach 4G (150Mbps) speeds if the local network permits it, it can also fall back to 3G or even 2G networks if required – very handy if you're travelling in remote regions where the infrastructure might not be what you're used to at home.

This is best suited to people who know what they're doing when it comes to international SIM cards.ĤG speeds up to 150Mbps are supported with this particular portable Wi-Fi hotspot, and it charges over a standard USB cable (Huawei says you can expect around 12 hours of use between charges from the 3,000mAh battery).

You do have to buy your own local SIM card for all the countries that you visit with the Huawei E5577-321 – while that does add to the cost and the setup time, it also gives you a lot of flexibility when it comes to picking data packages and network providers. Huawei knows a few things about making gadgets of course, and this hotspot is compact and well-built – it's perfect for popping in a bag and suitcase and taking with you wherever you go, whether that's within the UK borders or beyond. there's not much more you can ask from the Huawei E5577-321.
