Most cellular calls are made in the same region, while international calls are commonly connected through Wi-Fi. Every country has a different prefix (the first two numbers of your phone number, like 1 for the US). Because of this, whenever you dial a phone number there is an automatically assigned local prefix. This is what ‘Dial Assist’ does.
The automated feature can be an issue when you’re trying to contact someone with a foreign number or a different prefix. By disabling ‘Dial Assist’, it gives you the guarantee that the number you dial is the one that’s going to receive your call.
