Why 0300 200 3310 fails from a foreign phone
On a toll-free number, HMRC Self Assessment pays for the call instead of you. Carriers generally only route these calls from networks inside the area the number covers, here the UK. A call from a foreign SIM, or from a home SIM roaming on a foreign network, has nobody to bill it to, so the network rejects it. You usually hear "your call cannot be completed as dialled", a fast busy tone or silence.
That's why HMRC Self Assessment lists +44 161 931 9070 for callers outside the UK. Dial that one with VoixCall.

How Much Does It Cost?
VoixCall charges by where you're calling, not where you are. Calls to numbers in the UK cost 3¢/min to landlines and 5.2¢/min to mobiles. At the landline rate, a 30-minute call to HMRC Self Assessment, hold time included, comes to about $0.90.
Your first call is free. After that you pay from prepaid credit, with no subscription. Recording adds $0.003/min. Rates as of 2026-10-06; see current rates for the UK.
Record the call and keep the reference number
A call to HMRC Self Assessment usually ends with a case or reference number and a promise about what happens next. After a long hold, in a second language, it's easy to miss a digit.
Switch on Record on the VoixCall dialer before you call ($0.003/min). If you've also turned on "Record and transcribe my calls" in Settings in the web app, about a minute after you hang up Call History shows a short summary, the reference numbers that were said (each with a Copy button), what each side agreed to do next, and the full transcript, for $0.02/min.
Recording is off by default. HMRC Self Assessment hears a short recording notice when the call connects, and only you can see your recordings and transcripts. Speech-to-text can mis-hear fast numbers, so check important digits against the recording. Recording laws differ by country. How call transcripts work →
