Can I use a sim card from my Lg G3 for an Iphone 6 or 6 plus if i cut it to make it a Nano sim card?
Will cutting it to a nano sim card work?
Should work fine. I had to cut a micro SIM to nano size because i was in the middle of nowhere. Use a template to draw the lines where to cut and use some good sharp scissors. You'll probably need to file any rough edges and file the back to make it slightly thinner. You can also use sandpaper.
Yes, provided the iPhone 6 or iPhone 6 plus is not locked with a different network. If it is, then you need to unlock it. To unlock, I suggest you can approach Theunlockspot.com and specify the country,locked network of phone.Based on the availability you can get the permanent unlock service along with free instructions.
