On mobile, your call button is useless most of the time

On a site seen from a phone, the call button is often the most visible way to get in touch. Someone still has to pick up.

Mobile’s share in France

According to StatCounter, smartphones accounted for 57.1% of measured web traffic in France in 2025, against 40.6% for computers and 2.3% for tablets. The monthly share varies a lot from one month to the next, which is a reason to reason over the year rather than a single month.

Crossed with your opening hours

If you are open 9 to 5 on weekdays, you are closed 77% of the hours in the year. Assuming traffic is spread evenly, 44% of visits would be both on mobile and out of hours. For those visitors, a call goes to voicemail at best.

The assumption is rough: a business site probably gets more visits during the day. But even halved, the share remains significant.

Match the buttons to the time of day

• During opening hours, keep the call button: it is the most direct contact.
• Outside them, replace it with a way to get in touch that works at that moment, such as a chat agent.
• Avoid stacking: a contact bar and a chat bubble on top of each other make three options for a single intention.

That is the rule used on alyor.fr: on mobile, the chat takes the call button’s place when the office is closed.
