Unlike other smartphones, the iPhone’s keyboard doesn’t have a row of numbers at the top; instead, every time you want to insert a number into a sentence, you have to switch between two keyboard modes: letters and numbers/symbols.
However, There is a little-known trick that can speed up typing when entering numbers.
If you need to enter a number, just do it Press and hold the 123 key with one finger while using the other finger to press the numbers you want to enter. As soon as you release your finger from the key, you return to the main letter block.
If you only need to enter a number, you don’t need to use more than one finger as you simply need to hold down the 123 key and drag the same finger to the number you want to press.
This trick will make it easier and faster to write messages to your friends and family who need numbers.
