I found recently that my usual internet connection was down quite alot in my area the router would always need to be reset or turned off and on because it got quite hot.
I decided to look online for a different method as a back up forwhen my router was down and have to wait hours and hours to be fixed.
After a few days i found an advert for a usb dongle which was a great idea i went to my local store and enquired and i purchased a lovely pink usb dongle on the network t mobile, i just had to insert the sim card provided into the usb pen and top it up with the chosen amount of credit this varies on the usage you want out of the usb dongle.
With t mobile they offer great deals so i put on Â£10 and that gave me unlimited access to the internet for a month!
Its a great way to have internet access if your main method goes wrong or gets disrupted,
The installation is very easy just plug it into the port on your pc or laptop and an on screen instruction script appears which does everything for you!
I highly reccommend this to anyone who wants or needs a back up method .
The only downfall is getting a good signal and that depends on where you live for example i have to put my laptop on the desk in kitchen to get good signal and its not as fast as a normal router but it has saved my day a few times now and give this a ten out of ten.
