There is no nether in Minecraft PE at the moment.
first you will need to obsidian in a reveane or somewhere where lava and water crashes together. I suggest you should mine it with a diamond or netherite pickaxe. Collect enough to make the portal. Light it up with flint and steel or fire charge. Go in side of the portal. Once you get to the other side of the portal, crack a netherract block. Do you see a letter Y when you are cracking the netherract block? Head in the direction the letter Y is pointing and you may find the Minecraft Nether Fortress
You have to build a portal with obsidian
Make a nether portal.
