There are many types of waterproof phone cover options available in the market, and each one has its own benefits. The most common type is the pouch-style cover. This type looks like a small transparent bag that you can open from the top. You place your phone inside and close the lock to seal it. This type of cover fits all phone sizes, so it is very flexible. It is great for swimming, beach trips, rain, and travel. There is also a universal waterproof phone cover that fits many phone sizes but has more structure than the basic pouch. It may have additional features like shock absorption, floating ability, or extra space to store cards or cash. Many travelers prefer this type because it offers multi-purpose use.
