I press the call button and nothing happens. What is wrong?

The button is switched off, not broken. CallTuv turns it off until the number is complete for the country selected, a team is active, there is credit for at least 3 minutes at that number's rate, the price check has finished, you are online, and you are not already in a call on another device. On a phone the microphone must also be allowed. The reason is usually written on screen just above or below the number you typed.

I have credit but no calls will go through at all. Why?

Credit on its own is not enough. Starting a call needs credit for 3 minutes at that destination's rate, so a small balance can still be too low for an expensive country. It is also worth checking that a team is selected, that the number is complete for the country you picked, and that you are not already in a call somewhere else.

My call was unsuccessful. What does that mean?

Open History and look at the status on that call. No answer and busy both mean the call reached the other phone and was not picked up. Failed means the network could not put the call through at all, which usually points at the number itself. Canceled means it ended before it connected.

Am I charged for a call that did not connect?

No. Only connected calls are charged. If you see a charge against a call that never connected, that is worth reporting so we can put it right.

The number looks right but every call fails. What else can I try?

Switch your caller ID to Shared Numbers and call again. Switching is instant and free, and it tells you whether the destination network was refusing calls that showed your own number. Also check the number with the person you are calling, since a failed status most often means the number cannot be reached as dialled.

Can I check whether a number is reachable before I call?

Type it into the dialer. CallTuv checks the format as you type, tells you whether it is a landline or a mobile, and shows the exact price. That does not prove the phone is switched on, but it does catch a wrongly typed or impossible number before you spend anything.

Why Your Call Won't Connect

A call that won't start (or drops within seconds) is frustrating - the good news is it almost always has one of a few simple causes. Find the message you're seeing below and we'll get you calling again. If you're seeing no message at all, start with the next section.

You press the call button and nothing happens

If you tap the green call button and nothing at all happens - no ringing, no error, no sound - the button is switched off rather than broken. CallTuv turns it off whenever a call couldn't succeed yet, so you never spend credit on a call that was going to fail. Having credit on the account isn't enough on its own; every one of these has to be true before the button wakes up:

The number is complete. Until what you've typed matches a real number for the country selected, the button stays off. You can see this happening: once CallTuv recognises the number it tells you whether it's a landline or a mobile and shows the price per minute. If you see neither of those, the number isn't ready to dial - check the digits and the country against Entering Phone Numbers and Choosing Countries.
A team is selected. Calls are made from a team's balance, so if no team is active yet the button stays off. Pick one in the team switcher - see Creating and Switching Teams.
There's credit for at least 3 minutes at that number's rate. This is the one that surprises people who do have credit. A balance of $0.20 is real money, but if the destination costs $0.30 a minute you need $0.90 before the call can start. Minimum Balance to Start a Call explains it, and expensive destinations make the gap bigger than you'd expect.
The price check has finished. For a second or two after you finish typing, CallTuv is looking up the exact rate for that specific number. The button is off while it works and comes back on by itself. If the check can't complete, you'll see "Unable to validate this number right now" - that's usually the internet connection.
You're online. If the connection drops, calling is switched off until it returns. Refresh the page or reopen the app once you're back.
You're not already in a call. Only one call at a time is possible on an account. If another browser tab, another device, or the app is on a call, this screen says "You are already in a call" instead of the dialer. End that call first.
On a phone, the microphone is allowed. The app can't place a call it wouldn't be able to speak through, so it asks for microphone access first - see Fixing Microphone and Audio Issues.

One last thing worth knowing: if the button says Connecting… rather than Call, the call is already on its way and pressing again does nothing. Give it a few seconds.

Whenever CallTuv has a reason it can tell you, it writes it on screen just above or below the number you typed. It's easy to miss because it isn't a popup - so before anything else, read the small print around the dialer.

"Insufficient balance" or a top-up prompt

Starting a call needs credit for at least 3 minutes at the destination rate - see Minimum Balance to Start a Call. Owners can top up; members should ask their team owner. If the call connected but ended on its own, the balance likely ran out mid-call - auto top-up prevents that.

"Invalid phone number" and format errors

The number doesn't match the selected country's format - usually a wrong country selection or a mistyped digit. See Entering Phone Numbers and Choosing Countries for exactly how CallTuv validates numbers, or run the number through the free phone number validator.

"Select a team before placing a call"

Your session has no active team - pick one in the team switcher and dial again. See Creating and Switching Teams.

Connection and network errors

Messages like "Connection Error," "Connection timed out," or "Unable to retrieve Voice token" point to your internet connection or a blocked network:

Check your connection is actually online, then refresh the page (web) or reopen the app (mobile) and try again.
Disable a VPN if one is active.
Corporate or public networks sometimes block internet calling - try a different network or a mobile hotspot to confirm.

Microphone blocked (web)

If the browser can't access a microphone, the call can't start - errors like "This browser does not support microphone access" or a permission prompt you dismissed. Fix permissions per Fixing Microphone and Audio Issues.

What the result in History tells you

When a call doesn't work, the single most useful thing you can do is open History and look at the status on that call. It tells you how far the call got, which narrows the cause straight away.

Completed - the call connected. This is the only status that is charged.
No answer - the call reached the other phone and rang, but nobody picked up. The call did go out; this is the destination side, not CallTuv.
Busy - the line was engaged. Again, the call went out and reached the network.
Failed - the call could not be put through at all. The destination network refused it or the number could not be reached as dialled. This is the one that most often means something is wrong with the number itself.
Canceled - the call ended before it connected, usually because it was hung up while still ringing.
Ringing, In progress, Queued - live states you'll only see while a call is actually happening.

No answer, busy, failed, and canceled all mean the call never connected, so none of them are charged. If you think you were charged for one anyway, Charged for a Call That Didn't Connect? explains what to check.

Check the number itself

A failed status points at the number more often than anything else, and it's worth a minute before trying again.

Read the digits back. Compare what you dialled against what you were given, digit by digit. One wrong or missing digit is the most common cause of all.
Check the country. Make sure the country selected in the dialer matches where the person actually is. If you have the full international number starting with +, type it that way and CallTuv works out the country itself. Entering Phone Numbers and Choosing Countries has worked examples.
Watch what the dialer says as you type. Once the number is complete, CallTuv tells you whether it's a landline or a mobile and shows the exact per-minute price. If it can't recognise the number at all, it isn't a dialable number as typed.
Confirm the number is still in service. The dialer can tell you a number is well-formed, but not that the phone is switched on, in range, or still connected. If you can, message the person and ask them to confirm the number, or ask someone else to try it from an ordinary phone.
Give it time and try again. Networks abroad have busy periods and temporary faults. A number that fails now can work perfectly an hour later.

Try the other caller ID

This one is quick, free, and rules out a whole category of problem in a single call.

If you're calling with your own verified number as caller ID, switch to Shared Numbers and try the same number again. Switching is instant and doesn't undo your verification - Switching or Removing Your Caller ID shows where the setting lives. If the call then goes through, the destination network was the problem, not your account.

Some destinations refuse a personal caller ID outright, and CallTuv tells you so before the call rather than letting it fail:

Singapore does not accept any personal caller ID, because of local anti-spoofing rules. Shared Numbers work normally.
Finland, Czechia, Thailand, and India don't accept a caller ID from that same country. A Finnish number calling Finland is refused; the same Finnish number calling anywhere else is fine.

Separately, if your own number connects but shows up oddly on the other end, Verified Number Showing as Private or Spam covers that.

"You have reached the hourly limit for calling new numbers"

There's an hourly limit on how many numbers you can call for the first time. Numbers you've called before are never limited, so your contacts, family, and any number already in your history all keep working.

Almost nobody reaches this. It's there to stop automated dialing through long lists of strangers, which is the behaviour that gets numbers blocked by phone networks - so the limit protects call quality for everyone.

The count clears at the top of each hour. If you have a genuine reason to call many new numbers - a call centre, an outreach team - contact us and we'll raise the limit on your account.

"Your team has reached the hourly limit for calling new numbers"

Same limit, shared across everyone on your team. One busy teammate can use most of it, so if you hit this and you've barely dialed, someone else on the team has been calling a lot of new numbers this hour.

Numbers anyone on the team has already called still work. It clears at the top of the hour, and we can raise it for your team the same way.

"No answer after several attempts"

You've called the same number many times in a row without it ever picking up. Rather than keep ringing it, we pause that one number for a while - every other number still works normally.

The most common cause is a wrong number, so it's worth checking the digits and the country code before trying again. If the number is right, give it some time - the pause lifts on its own, and it clears immediately once the number answers a call.

None of these match?

Contact us with the exact number you dialed and roughly when you tried, plus whether you're on web or mobile - with those details we can trace that specific call and see exactly where it failed.
