That's a brief, whistle-stop tour of what is quite a complicated and technical process. If you're serious enough about removing bloatware in this way, we'd recommend researching details for your particular phone model and reading more about ADB first, as well as consulting the excellent XDA Developers guide to the process (you might also find guides customized to your specific phone).

The second way to comprehensively pull out bloatware is to root your phone. As with ADB, this requires a little bit of technical know-how, but it'll also void your handset's warranty and introduce a (small) risk of bricking your device. It's a lot of trouble to go to to remove some unwanted apps, but the option is there if you need it.

If you think rooting is for you, it will give you full control over your phone and it's software. Again, XDA Developers has a detailed and comprehensive guide for all kinds of Android phones, and once you've modified your phone in this way you'll be able to make use of apps like Root App Deleter or System App Remover to get rid of unwanted apps.
How to Remove Bloatware on iPhones

You can remove stock iOS apps, though some data may remain in iCloud.

iPhones have much less of a problem with bloatware, because it's only Apple that makes it (Yes, the iPhone, and all the pre-installed apps that come with one.) You could argue that some of Apple's less necessary apps match the definition of bloatware, but you definitely don't get any third-party, largely useless apps that you weren't expecting in advance.
Some of those pre-installed, stock apps—like Safari and Messages—can't be removed, but since iOS 10 launched in 2016, Apple has allowed users to remove a lot of the stock apps if they don't need them. The apps you can get rid of include Calculator, Calendar, Compass, Contacts, FaceTime, Home, iBooks, iCloud Drive, iTunes Store, Mail, Maps, Music, News, Notes, Podcasts, Reminders, Stocks, Tips, Videos, Voice Memos, Watch and Weather.

To remove any of these apps, do the same as you would with a third-party app: Long press on the icon, then choose Delete App from the menu that appears. You'll then be shown a confirmation window, so hit Delete to finish the process. If you need any of these apps again in the future, you can find them in the App Store.
In some cases removing the app won't remove the associated functionality, which is actually built into iOS itself. Delete FaceTime, for example, and you can still make and receive FaceTime calls through the Phone app. The Phone app also keeps hold of your contact list even if you delete the actual Contacts app.
