How to make 200mb of data last longer?

I only have 200mb of data for my iphone.
and i don't want to go over. So is there any way to make it last longer.

i wanna surf the web and watch a lot of youtube videos but i can't…

Try to use Wi-Fi when possible like when you are home or at a public place with Wi-Fi. Don't stream video that take lots of data. There's no real way to make it last longer. All you can do is try not to use too much. You should get a larger data plan if you want it to last longer.

You could connect to a Wi-Fi connection where available. Also, if you leave the mobile connection on it still uses data even if you're not using the device to run data tasks i.e surfing the web, watching videos, using facebook. So I'd suggest turning your mobile network connection off when not in use. This will save your allotment, and also protect you from incurring any data overage charges. Hope this helps. P.S. Most newwr devices allow you to go in and set a limit for the data plan you have. So check that out too in your settings 8)

20Omb huh? There's a way but I don't think watching youtube videos will make your data to last longer… So for surfing I recommend you UC browser & turn on the lite mode in settings for google so that it will take only a few kb's like 5- 10 to load a page other than 100 - 200kb… For youtube there's no other choice other than watching with 144p… Hope this wud help!

Whenever possible, turn the data off and use Wi-Fi. When you do need to use data, turn it off when you put your phone away, because it could still be using data in the background to run tasks.

Also, wherever in the phone's settings you can turn off data, in newer devices there's an option to set a limit for data usage.
