Phone number must be a Singapore number doesn't fit the usage of the app

[julia-cp]

Actual: only Singapore phone number is valid

Expected: can be used for any countries phone number

Even if this is only used in Singapore, there are a lot of international people that may not have Singaporean phone number

:question: Issue duplicate status

Team chose to mark this issue as a duplicate of another issue (as explained in the Team's response above)

• [x] I disagree

Reason for disagreement: Even though the target users are NUS students, some students do not use Singapore phone numbers. Exchange students oftentimes don't change their phone numbers and international students sometimes don't change their numbers right away. So this should be a separate bug from not specifying the target user.

## :question: Issue type Team chose [`type.DocumentationBug`] Originally [`type.FeatureFlaw`] - [x] I disagree **Reason for disagreement:**  This issue can be considered as overzealous input validation, especially when it is quite possible that the user will need to enter a non-Singaporean phone number.

---

## :question: Issue severity Team chose [`severity.Low`] Originally [`severity.Medium`] - [x] I disagree **Reason for disagreement:** Even though by percentage there are not many students in NUS that don't have Singapore phone numbers, there are quite a lot of students who will interact with these students. Exchange students are also not that rare, we have about 2,300 exchange students from the total number of around 40,000 students. A significant number of students will interact with this population that may not have Singapore phone numbers. Therefore, by considering the target users, other countries' phone numbers should be allowed. This means this will cause inconveniences to some users. This is not a very rare situation. This is also not a minor inconvenience because the users will not be able to add these phone numbers.
