Calll scrambles then drops

[Wingersiow]

Since joining Vodafone my phone calls suddenly make a scrambling sound (like a tape playing fast) and then the call drops.  I have been with Vodafone for only a couple of weeks and my iPhone SE is about 6 months old and have never had this problem before,  Any ideas/suggestions.

Hi @Wingersiow

May I ask a couple of questions. 

• Does this happen at home or everywhere ?
• Did you Port to Vodafone from another Network ?
• Can you try your SIM card in another phone as a process of elimination ?
• Does this happen to Calls across all Networks and landlines ?
• Try turning off 3G in the iPhone to force 2G to see if this helps stabilise call quality. 
• Apple Stores have Genius Bars who can run diagnostics on the iPhone.

Vodafone has a Network Issues Template >  Here.

Hi,

Thanks for responding, in answer to your questions (although the problem hasn't arisen over the past few calls!):

• Does this happen at home or everywhere ?
  • It's only happened from my home
• Did you Port to Vodafone from another Network ?
  • Yes - from BT
• Can you try your SIM card in another phone as a process of elimination ?
  • Unfortunately not
• Does this happen to Calls across all Networks and landlines ?
  • I think it's only happened to landline calls
• Try turning off 3G in the iPhone to force 2G to see if this helps stabilise call quality. 
  • I'll give this a go - but it seems ok at the moment
• Apple Stores have Genius Bars who can run diagnostics on the iPhone.
  • Thanks.

@Wingersiow - Thanks for getting back to us.

Just to clarify a few things, please get back to us with the below answers:

1. When you’re away from home, are all calls to both mobiles and landlines ok?
2. If you’re at home and you call a mobile number from your phone, you say it connects ok?
3. Does this happen for every landline number you call, or just when calling a certain number?

Hi,

In answer to your questions:

1. When you’re away from home, are all calls to both mobiles and landlines ok?
   1. yes
2. If you’re at home and you call a mobile number from your phone, you say it connects ok?
   1. yes
3. Does this happen for every landline number you call, or just when calling a certain number?
   1. no, it apparently happens at random.  It doesn't always happen just every now and then - in fact it hasn't happend for a couple of days now,

Thanks

@Wingersiow Have you continued to receive any problems?
Please let us know

Hi,

Yes, in fact it happened 3 times this afternoon calling a landline - a different number to previous instances. Any ideas? Thanks.

@Wingersiow - This is strange. To eliminate it being a faulty phone, we’ll need you to test your SIM in another one for a few days.

I know you mentioned above that this isn’t possible. Please let us know your nearest Vodafone Store and we can check if they have a loan one in stock.
