The insider hookup is BACK and extended to September 30th!
There are 3 types of codes:
Type 1: 20% off Hookup
This will be the most popular by far. It will give customers porting in from AT&T/Verizon/Eligible MVNO 20% off all voice lines for the life of the account, even lines added later in the life of the account. This offer is stackable with pretty much all existing promos such as discounts on phones when you add a line, etc. This will also stack with third line free.
Type 2: $200 off a 5G phone for new customers
This one will probably be the least popular. New customers can get a code for $200 off a 5G phone. It will stack with other active promos, for example if a 5G phone has 50% off with add a line, etc. This type is only really useful for those opening a new account that isn't a magenta or magenta plus account, such as when opening a 55+ account or a first responder account.
Type 3: $200 off a 5G phone for existing customers
Existing customers can get a $200 rebate card when they purchase a new 5G phone from T-Mobile on an Equipment Installment Plan (EIP). No add-a-line necessary.
We have PLENTY of codes over on the subreddit (r/tmobile) and in the subreddit's Discord server (linked in the about/sidebar of the subreddit).
Q: What is a "Hookup Code"?
A: A hookup code is a unique code provided by T-Mobile and Sprint employees. Each employee gets 3 codes to hand out of each type. This code can be registered online along with your phone number to give you discounts, either 20% off the account or $200 off a 5G phone, depending on the code.
Q: I used a code. Now what?
A: If you got no error messages, you're all set. For the 20% off code simply visit a T-Mobile store to setup a new account and port in the number you registered the code with. You don't even have to mention hookup to the employee if you don't want to, everything will be automatic. For the $200 off code, you will use it after buying a new 5G phone on EIP and receiving the phone.
Q: I already have a T-Mobile account. Can I get this deal?
A: No. New accounts only. You would need to port in a number from a carrier that is not a T-Mobile/Sprint account or one of their MVNOs into a brand new account using an account holder that does not currently have a postpaid T-Mobile account.
Q: My number was on T-Mobile or Sprint in the last 90 days. Do I qualify?
A: No. In order to qualify as a new customer, the number you port in (and use for the insider hookup) cannot have been on T-Mobile or Sprint (or one of their MVNOs) in the last 90 days.
Q: Can I stack other promos?
A: Yes! 20% Hookup is compatible with pretty much all other promos like phone trade in deals.
Q: How much would my plan be with the 20% discount?
A: On Magenta, 1 line is $56, 3 lines is $112 (w/third line free), 4 lines is $128, and additional lines are +$16 each (up to 8 lines). On Magenta Plus, 1 line is $68, 3 lines is $112, 4 lines is $136, and additional lines are +$24 each (up to 8 lines). Both plans are taxes included, so what you see is what you pay.
