The people who use satellite phones will have used plenty of different phones throughout their lives. Almost everyone uses a smartphone now, or has used one.
Many people have memories of using landline phones with buttons, and they might still use them. Other people might prefer these phones, and they may have been using them the entire time. The experience of using all these different types of phones will often be unique, which is true for sat phones as well.
People who are used to making calls using smartphones might find the act of using a satellite phone memorable. These phones have buttons. Using a sat phone might feel like using a laptop keyboard to the people who are not familiar with some older phone models.
Dialing longer phone numbers is sometimes easier with a phone that has this sort of shape. A sat phone number will often be longer than other phone numbers in practice, which is important to remember.
People will usually dial twelve digits when they input their satellite phone numbers, since they will also have to add the prefix for the satellite phone provider. For the most part, the prefix will be easy to dial and to remember. Most of these prefixes will only be three digits long, which will add to the relatively short satellite phone number.
Most people are used to dialing ten-digit phone numbers, since the area code will often have to be included. A satellite phone number will include the prefix instead of an area code. However, the satellite phone number itself will usually be eight digits long or nine digits long instead of seven, which will slightly add to the dialing time. Still, the differences between satellite phone numbers and other phone numbers often won’t matter that much in practice.
