Promotions For Existing T Mobile Customers

There are 4 main ways to get great promotions from T-Mobile as an existing customer.

If you maximize the potential of these strategies, you can save $28.45 a month on your tmobile bill.

That’s about a 15.3% savings on your plan – less than other service providers. T-Mobile base plans do cost less than comparable Verizon and AT&T plans. The main ways to get existing customers T-Mobile discounts are the following:

  1. Upgrade your plan
  2. Downgrade your plan
  3. Have promotional/loyalty discounts applied
  4. Take advantage of special affinity plans

Let’s started on getting you some great deals!

T-Mobile Upgrade Deals For Existing Customers

The easiest way to get deals on T-Mobile as an existing customer is to upgrade your plan or switch your plan to a lower tier one that meets your current plan usage.

To respond to competition from AT&T and Verizon, tmobile constantly changes their plans to maintain and grow their customer base.

Their current regular tier plans are Magenta Max, Magenta and Essentials.

If you’ve been with T-Mobile for more than year, the plan that you’re currently on has likely been renamed or changed.

Most of the time, plan prices go down and the number of features go up.  Just because that’s the case doesn’t mean that T-Mobile switches you automatically to a plan that best fits your needs.

You’re going to need to do that yourself by calling tmobile customer support at (800) 937-8997.

Once you have someone on the line, ask them if there’s any way to save money on your plan.

Before you make the call, check T-Mobile’s current plans to see if you would save if you switched to one of them.

The agent will likely move you to one of the plans on the website.  While you’re on the line, ask their advice on which plan is best for you to move to given your usage.

The difference between many tmobile plans is free Netflix or higher mobile hotspot usage.  If you’re not using these features, you’re wasting your money.

These kinds of deals don’t require any negotiation skills or deep understanding of T-Mobile customer retention practices.

It’s basically switching you to current plans or aligning your plan to your actual usage.

Discounts For Existing T-Mobile Customers

Once you’ve confirmed that you’re on the best plan for your current usage, it’s time to see if you can get a discount on your current plan even if you’re an existing customer.

For this deal, you’ll actually need to negotiate to get a discount rather than having the rep just applying your plan for you.

You’ll start by asking the rep if you can get a discount on your existing plan.  It’s critical that you say that you’re thinking of leaving T-Mobile. You want to see if they have a better offer.

If you are a customer in good standing with tmobile, you’ll often be given a discount at this time.  Generally, they’re going to offer you a $10 recurring discount that will be valid for 12 months.

However, you can increase that discount by moving farther in the cancellation process.  Ask to be transferred to the T-Mobile retention department. They will give you additional discounts that you can get offered before you leave.

Once you get there, the loyalty department will generally increase your discount.  It’ll now be called a loyalty discount rather than a promotional discount.

The final and best method to fully maximize the loyalty/promotional discount you can ask is to ask to speak to a manager on the retention team.

Managers can override some of the system limits on discounts. By speaking to a manager, you’ll be able to increase your promotional discount from $10 to as much as $30 to $50 a month.

The discounts are generally last for a year but we’ve found that you can renegotiate after a year and get the discount extended.

Special Tmobile Offers For Existing Customers

The final way to get deals on your T-Mobile account is to see if you qualify for any special plans Tmobile has for affinity groups.

The main offers are 55+ plans, ACP and military and first responder discounts.

If you’re over 55, you can get 55+ plans where you can pay Tmobile $55 a month instead of $100 for a similar plan.

One of the catches about these plans is that you can only have two lines on this plan so you can’t sneak your entire family in.

However, if you have multiple seniors in your family, you can save significantly if you have multiple plans!  Also, if you just turned 55, move to this plan to lower your Tmobile plan significantly.

It’s not specific to tmobile but it’s possible to save $30 a month with the Affordable Connectivity Program (ACP) courtesy of the US government.

ACP is a government program started in 2020 to make sure lower-income Americans had continued access to phone and cable service during the lockdowns.

If you have on SNAP, Medicaid or your income is 200% of the poverty line, you can enroll in this program.  Please note that you have decide whether you want to use the program for your phone or internet service.  You can’t do both.

Finally, tmobile has discounts for people serving in the military or who are first responders.

The pricing for the military and first responder plans are the same.

You’ll need to verify that you’re a member of these groups on the Verizon portal using your credentials (generally your military or hospital id).

The savings for these deals are about 20% but you can have more lines on your T-Mobile plan compared to the 55+ plans.

T-Mobile iPhone Deals For Existing Customers

T-Mobile has a number of iPhone deals that existing customers can apply but most of these deals involve adding a new line to your account.

One that doesn’t involves getting an iPhone 12 for $400 off.  You’ll need to trade in a phone to take advantage of this promotion.  You can do this by trading in your old phone or buying a new phone second hand.

Make sure you’re going to get the full trade-in value before you buy an old phone to trade in.  Tmobile pro rates the $400 credit over 2 years.

The rest of the T-Mobile promotions for iPhones are some variation of get an iPhone for a discounted price if you add a new line and stay with us for 24 months.

One option is getting an iPhone 13 or iPhone SE for free when you add a new line.  There’s also a buy one get one free promotion for an iPhone mini.

Read the terms and conditions before getting one of these plans applied. You’re not going to get a great deal on a T-Mobile plan as an existing customer unless you bring new lines to them.

At least for iPhones, there’s not much reward for being a loyal customer so if you’re open to it switch to Verizon or AT&T to experience big new customer discounts.

T-Mobile Phone Deals For Existing Customers

T-Mobile also has Android phone deals for existing customers besides iPhone phone deals.

However, all of these phone deals involve you adding a new line to your tmobile account.

One promotion is getting a Galaxy Z Flip4 phone for free when you activate a line on Magenta Max. For a folding Galaxy phone, you can get $1,000 of discounts.  These will be bill discounts over 36 months though.

There’s also Google Pixel and Revvl 6 Pro deals as well.  None of them are particularly appealing.
