I am planning to travel to Asia for 5 weeks in the end of January and will be back in the beginning of March. So, for me for February, I think it's better to change my mobile and internet plan to the cheapest one, and switch back before my return. I will use the local SIM card during my trip. The cheapest internet plan is $30/month and $10/month for the mobile plan. Does anyone have any suggestions? Can I suspend both services and reactivate them later on?
