If you’re an iPhone user, there’s a high chance you’ve come across this message at some point:
“iPhone Storage Almost Full” or “Not Enough Storage to Take Photo.”
It’s frustrating, especially when you’re trying to capture a moment, download an app, or install a system update. So, what can you do when your iPhone runs out of space?
The good news is—you can buy more storage. But not in the traditional sense.
Unlike computers or Android phones with expandable SD cards, iPhones don’t allow you to physically increase internal storage. However, Apple provides cloud-based and upgrade-based solutions that offer extra room to store your photos, videos, messages, backups, and apps.
In this in-depth article, you’ll learn how to buy more storage on your iPhone, what it actually means to “add storage,” and the best ways to manage space so you never see that dreaded “Storage Full” message again.
Understanding iPhone Storage vs. iCloud Storage
Before we jump into solutions, it’s important to understand the difference between the two types of storage Apple offers:
🔹 iPhone Storage (Internal Storage)
- This is the built-in memory of your device (e.g., 64GB, 128GB, 256GB, etc.).
- It cannot be upgraded or expanded after purchase.
- All your apps, photos, videos, system files, and downloads live here.
🔹 iCloud Storage (Cloud-Based)
- Apple’s online storage service that syncs data across all your Apple devices.
- You can buy more iCloud storage anytime via subscription.
- It stores photos, backups, documents, messages, and more.
So when people ask, “How do I buy more storage on iPhone?”—they’re usually referring to purchasing additional iCloud storage, since physical iPhone storage upgrades aren’t possible post-purchase.
Part 1: How to Buy More iCloud Storage on iPhone
iCloud is the fastest and easiest way to expand your iPhone’s usable space without deleting your personal data.
Steps to Upgrade iCloud Storage:
- Open Settings
- Tap on the Settings app on your iPhone.
- Tap Your Name (Apple ID) at the Top
- Tap iCloud
- Tap “Manage Storage” or “iCloud+”
- Tap “Buy More Storage” or “Change Storage Plan”
- Choose a Plan:
- 50GB – Ideal for basic users (photos, backups)
- 200GB – Suitable for families or media-heavy users
- 2TB – Best for professionals or multiple-device users
- Tap Subscribe and authenticate with Face ID, Touch ID, or passcode.
Your iCloud storage is now upgraded, and your iPhone will begin using that space for photos, videos, backups, and files.
What iCloud Storage Can Do
Here’s how upgrading iCloud storage benefits your iPhone:
- Automatically back up your device daily
- Store all your photos and videos in full resolution
- Sync messages and attachments across devices
- Keep files in iCloud Drive, freeing up local storage
- Use Family Sharing to split a 200GB or 2TB plan with others
And best of all, iCloud works in the background, so once it’s set up, it requires little to no effort from you.
iCloud Storage Pricing (as of 2025)
Pricing may vary slightly by region, but here’s a general overview:
| Plan | Storage Amount | Monthly Price (USD) |
|---|---|---|
| Free | 5GB | $0 |
| Basic | 50GB | ~$0.99 |
| Standard | 200GB | ~$2.99 |
| Premium | 2TB | ~$9.99 |
Family Sharing is available for 200GB and 2TB plans, allowing up to five other people to share storage.
Part 2: How to Use iCloud to Free Up iPhone Storage
Buying more iCloud storage is just the beginning. You also need to offload data from your internal iPhone storage to the cloud.
Here’s how:
🔹 1. Enable iCloud Photos
- Go to Settings → Photos
- Toggle on iCloud Photos
- Choose Optimize iPhone Storage
This keeps a smaller version of each photo on your device while uploading the full-resolution version to iCloud, saving gigabytes of space.
🔹 2. Back Up to iCloud
- Go to Settings → Apple ID → iCloud → iCloud Backup
- Turn on iCloud Backup and tap Back Up Now
This removes the need for full device backups on your iPhone’s internal storage.
🔹 3. Store Messages in iCloud
- Go to Settings → Messages
- Tap iMessage and turn on Messages in iCloud
Older messages and media attachments will move to iCloud, freeing local space.
🔹 4. Use iCloud Drive
Move documents, PDFs, and other files to iCloud Drive:
- Go to Files app
- Tap Browse → iCloud Drive
- Move files from “On My iPhone” to “iCloud Drive”
Part 3: What If You Want to Physically Expand iPhone Storage?
Although Apple doesn’t allow hardware upgrades, there are a few alternatives:
🔹 1. Upgrade to a Higher Capacity iPhone
If you’re constantly running out of space, consider trading in your current phone for a model with more built-in storage, such as:
- From 64GB → 128GB
- From 128GB → 256GB or higher
Check trade-in values through Apple or carriers to reduce the cost.
🔹 2. Use External Storage Devices
Some third-party accessories (like Lightning flash drives or Wi-Fi external drives) can be used to offload large files like photos or videos.
These devices plug into your iPhone’s charging port or connect wirelessly. You can move files off your phone and store them externally.
🔹 3. Use Cloud Alternatives
Besides iCloud, there are other cloud-based platforms that offer additional storage and allow you to sync photos, documents, or videos. These can complement your iCloud plan or serve as an alternative if you’re low on space.
Part 4: Tips to Free Up Space Without Buying Anything
Before spending money, try these free methods to make space:
🔹 Delete Unused Apps
- Go to Settings → General → iPhone Storage
- Review apps sorted by size and delete what you don’t use
🔹 Offload Unused Apps (Without Deleting Data)
- Enable Offload Unused Apps under iPhone Storage
- This removes the app but keeps its data intact
🔹 Clear Safari Cache
- Go to Settings → Safari → Clear History and Website Data
🔹 Remove Old Messages
- Go to Settings → Messages → Keep Messages
- Set to 30 Days instead of Forever
🔹 Review Downloads and Attachments
- Delete media-heavy iMessage attachments
- Open Files app or Downloads folder and remove unused items
How to Check iPhone and iCloud Storage Usage
You should periodically review how your storage is being used.
Check iPhone Storage:
- Go to Settings → General → iPhone Storage
- You’ll see a graph with breakdowns by category (Photos, Messages, Apps)
Check iCloud Storage:
- Go to Settings → Apple ID → iCloud
- Tap Manage Storage
This gives you a clear picture of what’s using the most space and helps you prioritize.
Frequently Asked Questions (FAQs)
Q: Can I add storage to my iPhone like an SD card?
No. iPhones do not support SD cards or expandable memory. Your only option is to use iCloud or upgrade to a larger-capacity device.
Q: What happens if I stop paying for iCloud storage?
You won’t lose your data immediately, but you’ll be unable to upload new data. Eventually, iCloud services (like backups and syncing) may pause until you upgrade again or free up space.
Q: Does iCloud storage affect my iPhone’s speed?
No. iCloud does not impact performance. In fact, freeing up local storage through iCloud may improve your iPhone’s responsiveness.
Q: Is 50GB enough iCloud storage?
It depends. For light users who want to back up their iPhone and store some photos, 50GB is often enough. Heavy photo/video users may need 200GB or more.
Q: Can I share my iCloud storage with family?
Yes, the 200GB and 2TB plans support Family Sharing for up to six users.
