Well it will depend on if it is just a pop4 or a pop4+. The + can only handle a card up to 32GB. Where as the other can handle one up to 256MB. Quite a difference there.
Here are the specs pages on them...

No matter which you have, it should be running Android "Marshmallow", so you should be able to set the SD Card as "Internal" storage so that you can run apps from it. Below are the instructions on how to set it.
NOTE: If the manufacturer has restricted this option, which some do, then there is no way to make the card "Internal" rather than "External" storage. In such a case you would be better served moving photos, videos and music over to the SD card, since it would not allow for apps to be move, to free up space.
How to turn external SD card into internal storage on "Marshmallow".
NOTE: Please be sure you start with a blank SD card. It needs to be blank because when the card is converted to "Internal" storage, it will be formatted (wiped) and encoded (making the cards data only readable by that device).
1. Go to device “Settings”, then select “Storage”.
2. Select your "SD Card", then tap the “three-dot menu“ (top-right), now select “Settings” from in there.
3. Now select “Format as internal”, and then “Erase & Format”.
4. Your SD Card will now be formatted as internal storage.
5. Reboot your phone.
NOTE: If you don't reboot the phone, many things may not work correctly, so make sure you do.
