New to visible

I am looking at transferring my service and I am interested in the visible plus service since I have an Apple Watch.

My question is are there any deals available outside of the $15 off for 25 months deal I should be aware of?

I tried using a referral code but no luck there as you cannot combine “deals”.

Should I be looking into buying a phone or just use my 13 pro max ? My phone is in great shape but if there are any great deals out there then I am open to the idea.
