Why a call to Thailand fails

O2 blocks international calls on a £0 Spend Cap

A £0 Spend Cap on O2 bars chargeable use outside the monthly and Bolt On allowances. International calls are in that group, so the call fails.

O2, What are spend caps?

From any country, a call to Thailand also fails when

  • The 0 is still in the number
  • Your own exit code, not Thailand's
  • The number does not take calls from abroad
