Do i have to update regulary?

Hi friends. I bought Iphone X. In software update it shows me that there is new update that fix some issues but it wont allow me to do it because i am on my celluar network. Currently i am away i wont have access to my home Wifi for some time now. I read it wont run even if my cell network plan is very high. Is it of extreme importance to do that update or it can wait for a while, couple of months maybe. Or shall i search for wifi connection to do it right away

Personally, I would search for a free WiFi site and do the update. It contains some security things that you might need. On the other hand, if that is really difficult to do, you will have to wait.

I've seen your other posts so don't know if you have moved on but, personally, I tend to wait a while before installing updates to see if anyone else has any problems with it.

I will wait for a while with the update. Thanks all

You can turn off Notifications of updates, and also, disable the automatic download (of OS updates), feature. Then you can update, or check for updates, on your schedule.
