Example 1

If they will let me go to the university, will/do/should I call you or message you?

Example 2

If I will need the service you provide, will/do/should I call you or message you?

Which one is acceptable?

The if-clause is in a future sense. But is the "will" needed?

In the main clause, which one do I use? Will or Do or Should?

    There is no "will" in an "if" clause. "If" + simple present creates the future meaning on its own

Will is not needed.

If I need the service you provide (at some time in the future is implied), should I call you?

Do could be used instead (in the sense is it the proper thing to do?)
