If your phone is running out of space and you constantly have to delete photos just to take a new one, then it’s time to find extra storage capacity. If you have a phone with an internal microSD slot that’s a simple solution, just make sure the card is compatible with your phone. However, phones with internal expandable storage are becoming less common and it’s a feature you won’t have with iPhones.
In most cases, the easiest way to increase your phone’s storage, and hopefully increase its usefulness, is to take advantage of the many cloud storage options. A free Dropbox account comes with 2GB of cloud storage and Google Drive has 15GB of shared storage space. An Apple iCloud account comes with 5GB of free storage. And all of these cloud services allow you to increase your storage space for a fee.
