Re: Can I updating my lumia 535 using mobile data
Welcome to Windows Central Manmee,
The error you got indicates that your wifi is not stable/to slow.
Do you know the wifi speed?
Updates can not directly be downloaded with mobile data. But there is a work around for that but you need a second phone.
On the second phone you have to enable internet sharing and then connect your 535 to this wifi hot spot and then you can download the update.
But this only will work if the mobile data connection is fast enough and stable so on 2G it probably will not work.
You could by the way put your SIM card (with mobile data) in the second phone if you want to use your own mobile data.
