Welcome to Vodafone Community
Since this morning my iPhone 6s has been unable to connect ot the Vodafone network.
It's 'searching' and it sometimes comes online if i switch the handset off multiple times, i feel there could be something wrong with the phone internally.
I have installed the latest IOS a few weeks back so i know the issue isn't an upgrade in software.
May I ask a few questions.
Does this happen wherever you go or is it in one place ?
If one place check your masts via Vodafone uk-coverage-map.
Does this happen if you try your sim card in another phone?
If so then a Vodafone High street Store can replace your sim card.
If not then an Apple store can help via a diagnostic.
Can you try another sim card in your iPhone to test the iPhone ?
Can you try choosing another network and then switch back to Vodafone.
