bought iphone 11 used, was able to reset eveything but still wont make calls or text. Ran IMEI and says locked. I was able to do everything except call/text, how do i remove the lock, guessing seller erased info from phone but still linked to icloud

If the phone is carrier locked, then only the carrier can unlock it. Contact the seller and ask him/her to contact the carrier and ask that the phone be unlocked. In order to use the phone, you need to have an account with a service provider. They will provide their SIM card which you must install in our phone.

If you meant to say the phone's Find My activation lock is still active, then see the following:

Activation Lock Problem

If you purchased the device second-hand, then it is useless without the Apple ID and password to which it is locked. If you don't have it, can't remember it or cannot get it, then the device is useless to you. Try to get your money refunded, if you can, or take it to an Apple store for an exchange provided they will help you. If you are the original owner, then take the device, a copy of your purchase receipt and identity proof to an Apple retailer where they may be able to assist you. For a deceased owner, you will need a certified copy of the Death Certificate, the device, proof of inheritance and proof of your identity. Take all to your local Apple Store for help. Note: there is no guarantee that anyone can gain access to the device.
