You will not be getting a phone today.
Once the loan company have completed their thorough credit check you have to accept or decline any loan offer that they make (if you do not accept the offer nothing will be ordered and your credit history is unaffected).
Only when you accept the offer is anything actually ordered and it is then delivered on the next business day. So, if you accept today the earliest that a phone will be delivered is Monday.
If you desperately need a phone today then you will need to buy it elsewhere, sorry.
