Сомневаюсь, что текущее затруднение в привязке мобильного телефона в способ оплаты связано с войной.

Не совсем понятно на чьей стороне проблема оператора связи или Apple.

The only one of those two you can still ask is the carrier, who provide the finance.

From Apple support ...

Payment methods valid in Russia

• Apple Account balance (from redeeming App Store & iTunes Gift Cards or adding funds)
• Mobile phone billing
  • Beeline
  • MTS

Mobile billing is available only with supported carriers. This list is subject to change. Learn more about carrier billing.

If you still don't see an option to use a mobile number, your carrier might not support mobile phone billing.

I doubt very much if payment by mobile phone is available in Russia. Whilst the illegal war and sanctions persist, it will be very difficult to set up new payment methods.
