How to see a customer's screen during a phone call

Why is seeing a customer's screen on a call hard?

Seeing a customer's screen during a phone call is hard because the call and the screen live on different systems. The customer is talking on a regular phone line, often on the same phone they need help with, and most screen sharing tools were designed for meetings or IT technicians rather than a quick look in the middle of a call. Asking a confused customer to install a meeting app, create an account or read back a session code adds friction at the worst moment. The approach that works best keeps the phone call going, sends the customer one link by text or email, asks for one clear approval, and lets the agent watch from whatever device they have. The agent then guides by voice. Before choosing a tool, answer three questions: what device is the customer on, do you need to control it or only see it, and is the problem inside your own website or anywhere on their screen?

What are the options for seeing a customer's screen?

• Meeting link. Send a Zoom or Google Meet link and ask the customer to share. It works across devices, but the customer must join the meeting; on an iPhone in Zoom, that means installing the app and tapping Share Content, Screen and Start Broadcast.
• Remote support tool. Tools like TeamViewer or Microsoft Quick Assist offer full control of computers. On iPhones, TeamViewer is view-only and says iOS does not allow remote controlling of iOS devices. The customer installs an app and reads you a code or ID.
• Co-browsing. A script on your website lets an agent see the customer's session on your site, often with shared navigation and no download. It only covers pages that carry the script, so it cannot see other apps or sites.
• Apple's built-in sharing. When both people use iPhones with iOS 26 or later, the Phone app can share screens during a one-to-one call. It only works iPhone to iPhone, so it does not help teams who answer on desk phones or computers.
• Phone-support link. With GuidedView, you text or email a one-time link, the customer approves on an iPhone, Android phone or computer, and you watch in any browser while the call continues. It is view-only by design.

What should you say when you ask to see the screen?

Consent comes first, and how you ask shapes whether the customer agrees. Be specific about what they will share, what you will see, and how they can stop.

• Say why. 'It will be faster if I can see what you're seeing. Would you be OK sharing your screen with me for a few minutes?'
• Say what you can and cannot do. 'I'll only be able to see your screen. I can't tap anything, so you stay in control.'
• Say how to stop. 'You can pause before typing a password, and you can stop whenever you want.'
• Give them an out. 'If you'd rather not, that's fine. I'll walk you through it step by step instead.'

A short call script

1. Offer

   'I think I can solve this faster if I can see your screen. Is it OK if I text you a link to share it? I'll stay right here on the line.'

2. Send

   'I just sent you a text with a link. Open it on the phone you need help with.'

3. Approve

   'It will ask you to confirm we're on a call, then tap Share. Your phone will ask permission to share the screen, so go ahead and allow it.'

4. Guide

   'Great, I can see your home screen. Tap Settings, the gray gear icon.'

5. Protect

   'Before you type your password, tap Pause. I won't see anything until you resume.'

6. Close

   'All set. I'm ending the session now, so I can no longer see your screen.'
