Tech, wifi and hotspot questions
 

Hello. I have a T- mobile phone with wifi Hotspot.I use my hotspot to get on my laptop.I am in a contract with T mobile.I plan on leaving them once my contract is over.At times, I am in areas that I cannot surf on my phone or the laptop.Are there any wifi apps I can download to use as a back up?.I know most companies will charge and thats fine , as long as the fee is reasonable.If you guys remember, back in the days , the service providers will help you create either a dialoup or network access icon and you can either VPN or access their internet servers to get on the net..I am wondering if there is such an app for wifi without having to buy any device.
