Chosen Solution
Okay so couple of days ago, my iPhone 7 Plus just randomly dropped out the signal and it started to show “Searching” instead and even if I removed the sim card it still shows searching, I’ve tried most of the solutions for this problem such as resetting the network, resetting all settings, changing the sim card which I placed different carriers, and here I end with the factory reset which I wish I never did, now I’m stuck in the setup mode, tried putting it nearby another iPhone didn’t work, shows me this type of error which says “Your iPhone could not be activated because the activation server is temporarily unavailable. Try connecting your iPhone to a Mac or to a PC with iTunes to activate it, or try again in a couple of minutes.” Then when I try activating with iTunes it shows “The iPhone “iPhone” could not be activated because the activation information could not be obtained from this device. Disconnect your iPhone. Make sure the SIM card is inserted.” Which something I already followed before so anyone please help me with this? Notice that I didn’t drop my phone AT ALL or no any type of damage happened to it in the period this happened.
This happens when the baseband CPU or the baseband power management chip has been damaged, either from heat, drop, bend or electrical. The phone needs information from the baseband CPU for activation and cell service. Unfortunately if you haven’t got the equipment and know how you will need to get it fixed at a repair shop.
