why can my phone have no reception but still say I could make an emergency call?
In: Technology
Because of something called ESN – Emergency Services Network, a common frequency that all carriers use, and all phones have access to, even if you’re not using the carrier that the cell tower belongs to.
Source: work in the telecoms industry building towers. Just finished a huge project to modify towers to run the ESN even when there’s a local power cut. Basically put ruddy great battery packs in.
