我帳號想更改電話號碼

没错。30天限制期后，您可以更改和更换恢复电话号码。

我还想补充一点，重新添加或添加另一个电话号码作为验证方式的做法，正如本文所述，Microsoft已逐步淘汰： https://support.microsoft.com/accounts-billing/manage/microsoft-account-security-info-verification-codes

Hey there! Nice to meet you!

Based on your description, your account has undergone a 30-day restriction period because you requested to change your account’s verification method (your recovery phone number).

Unfortunately, you will not be able to cancel the security info change request since you can't provide the codes from your previous recovery phone number.

You may check this link for more information regarding the 30-day security info change request: https://support.microsoft.com/accounts-billing/manage/what-does-security-info-change-is-still-pending-mean#:~:text=You%20were%20the%20person%20who%20removed%20the%20security,these%20security%20proofs%20to%20complete%20the%20cancel%20request.

Thank you for your understanding.

Best regards,
