Blow drying method not working for my iphone 4s anymore

Okay so one day my phone stopped detecting any networks so I had to do the blow drying method, the time time it worked for 3 days, the second time it lasted for a week, today i did it for the third time and it only worked for 2 hours… What do I do to fix this wi-fi issue?

Added (1). I don't have any service on my phone cause my mom can't pay for any so I have to relay on wi-fi

You should sell it to gazell or contact your Wi-Fi company because you need a new phone

Your phone is dead. You destroyed it by blowdriying it.
