Can't make phone calls?

So I've noticed every now & then I can't receive calls, or make them. There is no dial tone & after a few mins it just cuts off.

 

I've tried pinpointing the issue & I'm left clueless.

 

The only solution to fix the issue is to restart my phone.

 

I've tried turning data on & off. 

 

Using the sim 2 tray.

 

Toggling mobile data on/off. 

 

Turning WiFi calling on/off.

Trying different apn, nothing works.

 

Mobile data always active.

 

Literally at a loss. 

 

This doesn't happen

So I've figured something out.

 

If I ring a Vodafone number this occurs.

 

If I ring Giffgaff/O2 number this occurs.

 

If I ring my daughter's number first (Smarty) it rings, then after I hang up I can call Vodafone & Giffgaff numbers.

 

I can receive/send texts without issues.

I've also noticed when I'm on a phonecall with my partner or mother (Vodafone/O2) It will randomly hangup.

 

Haven't tested if this happens when I call a Smarty number

If restarting your phone seems to rectify the issue, this suggests it may be the phone. Have you tried the sim in another handset?

Have you also tried the same calls in a different location? Is it your local signal maybe? Does the handset always show a good number of bars for signal strength?

Good morning. I've tried the SIM in another phone & and SIM 2 slot.

In my home where calls are made the most I have full bar, 5G. 

Went on a little 1.2 mile walk & problem still persists

Same problem here for 6months unthought it was my phone .

Have you found a solution yet.

This type of issue could occur with a damaged or broken SIM card. 
Have you tried using a replacement SMARTY SIM card in your handset @GaryHud_1363877
You could try and request a replacement online at http://smarty.co.uk/dashboard/request-new-sim

Hi. Same problem too. I have two Sims in my phone. I've only had smarty maybe 6 months tops and I have randomly the same issue with not being able to make calls. But if I switch to my Vodafone SIM, without restarting my phone, it calls out fine. So it can't be a phone issue per say, but an issue with my phone and the smarty SIM card. Or the sim has an issue?

@Dnbkittie  Well worth requesting a replacement sim so that you can be sure.

I have the same problem. I do have some spare smarty sims at home. How do I get it to swap to my number etc?

@KevinHo_1918562  No, you need a specific replacement sim that they will send out.

 I am having a similar issue today, even restarting the phone, and even turning the phone off and back on, not just "restart", I can't even use WiFi calling to make a call, but I can receive SMS messages and yes I have checked my WiFi etc, so I guess I'll be ordering a replacement SIM I guess even WiFi calling requires validation of the SIM some how but SMS doesnt? strange.

If you are struggling with Smarty phone calling try typing *#*#86583#*#* in your dialer screen. Then go to network settings and enable VoLTE for your simcard.
