Overzealous input validation

[nus-pe-bot]

The restriction of phone number format seems to be overly restrictive, as the User Guide did not mention where exactly the target users may be staying. A lot of other countries have phone numbers that exceed (or are shorter than) 8 digits. Even in Singapore alone, since the app is supposed to manage contacts of students; a number of students may only have international numbers (e.g. if they just came to Singapore and have not gotten a local number yet).

Let alone the NOKs of these international students which may not even reside in Singapore at all.

They both point out the restrictive nature of our validation for the phone number.
