Can't make or receive calls.

[MichaelW]

Hi, I was wondering if someone could help. The issue started a couple of weeks ago where calls might drop randomly, but for the last week I've been unable to make or receive calls.

My phone can display a full signal, but if I attempt to make a call, either the signal just drops and the network becomes "unavailable", or nothing happens--no ring/call tone. From what family and friends tell me when I contact them through something such as Facebook messenger--on their end, it will either ring for a few seconds and go straight to voice mail, or tell them that I'm on another line. 

This happens both inside of my home, out in the open.

I've tried removing and reinstalling the SIM, resetting network settings on my handset, and even going far as a factory reset of the phone itself. 

I can, however, receive texts (thank goodness because of verification codes) and use internet data. I am PAYG. My phone is a little outdated, a Samsung Galaxy S7, but it does have 4G/LTE--and I'm mentioning this because I'm aware 3G is being phased out. I very recently topped up and did get a text confirming it--as well as addons appearing on my account dashboard. 

I hope I'm providing enough information here to troubleshoot.

Everything working as it should now with new provider (LycaMobile).

Even noticed that there is a new "Wi-fi Calling" option in my Call Settings. This month after 3 telling me it was a phone manufacturer issue. Useless.

It's like Three doesn't know what they are talking about, they announce switching off 3g and had no clue how it would affect customers. They only took care of customers who had three issued contract phones, for us customers on sim only contracts are expected to buy new phones or leave Three and some can't afford to

It does seem like they're trying to flog their current "sim only" customers. Their total disregard to addressing the issue is a disgrace and will NEVER use them for anything again.

I did a network reset still the same 😢 4g 3bars no calls.. 😑

Funny as I was in a town 10 miles from where I live the other day and my phone rang as normal...😂....?

Will be switching to another provider soon. 😏

I'm really liking the zero spam/scam calls 😂

Same issue, same excuses. Customer service is also useless. Switching provider will resolve the "issue" 

[Kb888]

Yes, Three actually told me I should leave to use another provider if I wanted to make and recieve calls, brilliant customer service.

Tried work SIM (EE) in my phone and was able to make/receive calls. Changes back and nothing. Despite having three bars. Was still able to send & receive SMS though.

Ordered new SIM off Lyca Mobile (EE Mast) and requested PAC code from 3.

Same for me I've got an ulefone armor x7 with 4g enabled can't phone or receive calls normally but can through WhatsApp?

She's got a Samsung a2core with 4g enabled same thing?
