The Galaxy S25 Ultra sits near the top of MTN’s Android range, with the built-in S Pen that no rival flagship matches. If you write, annotate or sketch on your phone, that single feature usually settles the model question before price enters it.
On MTN the variable worth attention is the data allocation. Plan tiers differ widely, and pairing a flagship instalment with a thin bundle wastes a large part of what you are paying for.
Compare the 24-month total across tiers, not the advertised monthly figure.

| What to compare | Why it matters |
|---|---|
| S Pen | Built into the handset — the Ultra’s defining feature |
| Monthly instalment | High on an Ultra; the 24-month total is what counts |
| Which plan tier | Determines the data and the advertised price |
| Data allocation | Check the anytime portion, not the headline figure |
| Storage size | 256GB entry point, and not expandable |
| Trade-in value | Substantial on recent Samsung flagships |
| Insurance | The outstanding balance is large if the handset is lost |
| Handset condition | New or certified pre-owned |
Pricing, bundles and stock change regularly. Confirm the current deal and the total contract cost with MTN before applying.
Compare by network, brand or budget
Against other networks. See Samsung S25 Ultra Telkom contract deals, Vodacom and Cell C.
Against the previous Ultra on MTN. The S24 Ultra carries the same S Pen at a lower instalment and is often the better value. See Samsung S24 Ultra MTN contract deals.
Against a standard S-series. Much cheaper without the S Pen or extended zoom. See Samsung S24 MTN contract deals.
Best-fit use cases
Use-case considerations
You use the S Pen. Note-taking, annotating documents, signing forms. Nothing else in the market substitutes.
You photograph a lot. The Ultra camera system is the strongest in Samsung’s range.
You use a lot of data. MTN tiers vary widely — on a flagship instalment, match the bundle to the handset.
You are trading in a recent flagship. Samsung and MTN both run trade-in programmes and the values can be significant.
You will not use the S Pen or the zoom. A standard S-series or an A-series handset saves substantially each month.
Budget is the binding constraint. The S24 Ultra gives you the same S Pen for less.

FAQs
Does the S25 Ultra include the S Pen?
Yes — built into the handset on Ultra models rather than sold separately. It is the main reason to choose an Ultra over a standard S-series phone.
Is the S24 Ultra better value?
Often, yes. It carries the same S Pen and similar everyday capability at a lower monthly cost. Compare the 24-month total of both before deciding.
Can I trade in my old phone on MTN?
Trade-in programmes are commonly offered and values on recent flagships can be substantial. Get the quote in writing before comparing deals.
Should I insure it?
Worth pricing. The outstanding contract balance remains payable if the handset is lost or stolen, and on a flagship that is a large amount.
What happens at the end of the contract?
The handset is paid off and becomes yours, but the plan commonly continues month-to-month at the same price unless you act. Diarise the end date and either move to SIM-only or upgrade — continuing means paying a handset-inclusive rate for service alone.
Can I keep my number if I switch to MTN?
Number portability applies between South African providers, so you can bring your existing number. Confirm the porting process and timing before switching, and do not cancel your old plan until the port has completed.
Can I expand the storage?
No. Recent Galaxy S flagships do not support microSD cards, so choose your storage tier at purchase — 256GB is the entry point on this model and you cannot add to it later.
