Perfect mobile data Sim for travel!

I have been using day's uncapped 10 plan in my phone and am very happy with it. I originally was going to use it in a router but then heard from support that it can be used in a phone. Apparently, I got an mtn mobile sim which means that I can use it in my smartphone. I am unable to spot my other devices, but it is worth it as mobile sim because it is really cheap compared to actual mobile data from my experiences. When travelling for work, for example, it has been very useful on the road. I only notice drops in signal when in remote areas between joburg and cape town, but otherwise it has functioned really well. If put in a mobile router like I am going to try, then I think that sharing data with other devices will work, but I need to find one. I will update my review if I remember, but so far anyway it is great! Again, very happy.
