I bought an internet SIM worth SAR 575 with 6 months validity... they told me I have a limit of 20 gb per week. But when I started using it... it gives 4g speed till 1 gb and then i receive a text from mobily that my internet usage is high and i will get interrupted services... I then I start getting 2g speed for that day... it happens every day...
So in a week I can only use 7gb with 4g speed.... rest I have to use it with 2g speed which is very bad...
Beware of buying the mobily internet SIM.
