The Samsung Galaxy S7 is one of the most popular Android phones, and for good reasons too. It has a fantastic screen, blazingly fast performance thanks to its Octacore processor, brilliant build quality and a very stable Android based operating system. It also come in a dual SIM variety, which enables you to run two different SIM cards within the one phone. There are a few reasons that you may wish to do this:
- Keep your work and personal number on one device
- Use a spare SIM on a different mobile network to improve coverage in rural areas
- Run SIMs from different countries for frequent travellers
Samsung’s dual SIM support always had an annoying quirk – you could only use 3G or 4G on one of the SIM cards; the second one had to fall back to 2G. This is fine in theory, as one SIM card will be for data and one will be for voice. However, in practise it becomes a problem. If you’re in the UK Three don’t have a 2G network at all, only 3G & 4G, and most mobile networks around the globe are starting to decommission their 2G networks in order to use the spectrum for 4G LTE. If you are in a rural area you may not even have a 3G signal. The result is No Service or Emergency Calls Only on the second SIM… which is not very helpful.
Roll on Android Nougat. This is the latest version of Android that is currently rolling out for the Galaxy S7. I updated my dual sim phone (the SM-G930FD) and found that all of a sudden, both SIM slots will run on 3G (with the main SIM running on 4G). This means that, when using a sim card on Three as the non-data SIM card, it will now be connected to the 3G network all the time.
Getting a dual sim S7. You won’t find the Galaxy S7 in stores in the USA or Europe, they’re generally sold in Asia. This means that you need to either buy it from an importer (see our article on importing a phone from China) or pick it up on Amazon. Luckily there are loads of dual sim S7 phones on Amazon (see here for the USA, or here for the UK).
