Repair loose blue coil without soldering?

I had done a home button repair on my iPhone and now, I have a really poor cellular signal. I suspect it is the blue coil loose since it looks misaligned and I tried checking the antenna cable. WiFi and Bluetooth is strong though. I have no soldering skills so I won't bother something like jumpering it. Is there any other way?

Also, if soldering is the only way, what is the difference between soldering back the inductor and bypassing it besides the difficulty in repair?
