I want to buy iPhone 15 pro max but if it’s discontinued will it make any problem?

Just because an iPhone is discontinued doesn't mean it somehow stops working. Discontinued just means that Apple is longer selling new units of that model. Your iPhone will continue to work for years to come. My iPhone was discontinued years ago and it works just fine.

So panic not. You'll be fine.

Regards.

As long as you purchase a "last of stock" phone from an Apple Store, or other authorized reseller, then there will be no problem at all.

Yes, Apple will maintain a stock of spare parts and replacement units for quite a while to come. Apple does not cease support for a device until five years after it was last sold.

Same here. I got the same phone today through my phone provider which is Sky (UK). Will I be okay as I only found out yesterday that they discontinued this phone?

Why wouldn’t it be OK? It does everything that it’s supposed to and has all features you read about for iPhone 15.

What if you have the iphone 15pro max and applecare and they need to replace the phone but they are discontinued? Will they have iphone 15 pro max in stock for replacement?
