Check that all permissions are activated and that your phone is not in power saving mode. Some devices like Huawei or Xiaomi automatically shut down apps that are running in the background to optimize phone performance. Please make sure that the tellows app is an exception, otherwise it cannot check incoming calls in real time. Therefore, check the app permissions in your device settings to ensure that the app can also be activated during lock screen, otherwise calls are only displayed when the screen is active, but not in inactive mode. Make sure that you have a good internet connection during incoming calls, otherwise the caller ID cannot take place or it will only be activated after a few seconds.

This feature requires premium. On the settings page, use the section: “Block incoming calls by local scorelist” to select which calls you would like to block. If you have premium, all calls from numbers with scores above the one selected will be blocked (e.g. score 8 and above).

A number must have at least 3 recent ratings and multiple search enquiries before it can be categorised as spam for all users. You should also check that the app is set to the correct country and check your settings to make sure calls with this score should be blocked.

In the menu click 'Upgrade to Premium', then 'Buy Premium'. Your app then automatically upgrades to the premium version.

The app requires Media, Phone, Caller information, Contacts, Identity and Storage permissions. We don’t use or share your personal data. You can decide which permissions you want to give, but the app's main functionality will be affected if permissions are missing. You can see the full details about our required permissions in the Play Store.

When you rate a number negatively it will be blocked on your device. Make sure, you activated the block feature in the app settings. You can find your local scorelist in settings.

Click on “Premium” in the menu and insert the code at the bottom of the page. Afterwards confirm the free period on top of the page via the Play Store. The free period is connected to the subscription. The activation only takes place after the completion of the free subscription via the Play Store.

Your subscription is transferred automatically as it is attached to your Google Play account.

If you used a coupon code in order to purchase premium, make sure that you applied it correctly (take a look at question number 6: "How can I use a Coupon code". Otherwise fore-close the app and open the app again.

Go to your “Local Scorelist”. You find all the numbers there, that you have blocked in the past. If you want to unblock a number just click on it and delete the entry from the list. If you want to whitelist a number that is blocked by the community blacklist, just leave a positive rating and it will not be blocked for you in the future.

It is compatible with Android 4.0.3 and up – check out the Play Store for further information.

If you use the free version, you need an internet connection to identify incoming calls. If you use premium, identification and blocking of numbers from the community blacklist doesn’t require an internet connection. If you want to search for numbers or add new numbers to your list, you need an internet connection to access our full phone number database.

What is the difference between tellows and its competitors?

In the ‘phone’ category of your iPhone settings, select ‘Call Blocking and Identification’ and activate tellows.

Unfortunately, this is a bug from Apple for all Caller ID apps. Here are some workarounds that you should try:

- If the app won’t activate in your iPhone, restart the phone and try activating the app again. It may take a few hours after the app has been installed for the first time until it is visible in the menu. We therefore recommend repeating these steps after a few hours

- If restarting does not help, please reinstall the app

- If you’re using other caller ID or blocking apps that also access the ‚Call blocking & identification‘ menu, make sure these apps are up to date or uninstall them. If one of these apps is stored in the cloud and is no longer installed, there may be problems with the ‚Call blocking & identification‘ menu for all other apps

- Make sure that no special mode is activated in the screen time settings, as this can block the list of apps displayed. Try reinstalling the app and restarting the phone if you have changed screen time settings

- Activate „Allow apps to request tracking“ in the iPhone settings under „Privacy“ → „Tracking“. The app should appear in the menu after restarting the iPhone
Open the contacts in your caller app from your iPhone and refresh the list by dragging from top to the bottom of the page

Open the app and click ‘update now’. You must keep the app running in the background for the blacklist to update itself automatically. After restarting the iPhone, the app must first be opened again manually so that the database can be automatically updated again from then on. Make sure, you allowed the update of the app database in the background by enabling it in the iPhone settings under "General" → "Background App Refresh".

A number must have at least 3 ratings and multiple search requests before it is categorised as spam for all users. Therefore, it can happen that some numbers are not yet in the blacklist, but are already showing ratings on tellows. You should also check that the correct country has been set within the app. If the comments of a phone number are highlighted in blue, this indicates that the wrong country is set. To adjust this, select Settings > Country.

It is important that call blocking is activated in the settings. You can set the score for blocking yourself.

Unfortunately, there is no way (until now) to see calls that have been blocked because it is not permitted by Apple to access this data and display it in the app.

In case you activated your mailbox, blocked phone numbers are directly redirected to voicemail. We cannot change this, because (as of now) Apple prevents Caller ID and Block apps to handle blocked calls differently.

Use the restore button on the protection page of the app (click on "Pro"). If it doesn't work, make sure you're using the correct Apple ID. Reinstall the app and restart the iPhone. You can find more information here.

Yes. You can benefit from family sharing by following this guide to activate the subscription within your family: https://support.apple.com/en-gb/HT201085.

Even though our database is giant, there is a limited memory space on phones. Therefore, we choose the spam numbers that are the most relevant ones. That means that in rare cases it can happen that a spam call with only a one or two comments and few searches does not get blocked yet. However, if many users rate a number, it will be included in the blacklist very fast.

You have to click on the “Protection” menu first. After that go to “Pro” and scroll to the bottom. There is a button that says “Enter coupon code”. After you typed the code in, you have to confirm the premium subscription. The activation only takes place after the completion of the free subscription via the App Store.

If you use pro, identification and blocking of numbers from the community blacklist doesn’t require an internet connection. If you want to search for numbers or add new numbers to your blacklist, you need an internet connection to access our full phone number database.

You can make changes to a company entry on our website independently at any time by directly navigating to the tellows website with your phone number and clicking the pen symbol at the "Details about this number" box. Company entries can only be added to numbers that have no rating above 7.

You can remove your company entry on our website at any time by directly navigating to the tellows website with your phone number and clicking the pen symbol at the "Details about this number" box.

Even though it will be removed on tellows immediately, please be aware that it can take some weeks until the cached information is not visible in search engines anymore.

On our site, your company entry is blocked for editing because it is either a premium entry or it was added by one of our data partners that manages entries for you. When you click the edit button on the entry, you can see on top of the page a message that explains whether it was a partner entry or a premium entry.

Premium entries can only be edited by tellows, so please get in touch with us via the contact form below. Partner entries have to be updated or removed by our partner otherwise the entry might get uploaded again. Please contact the partner company for adjustments on this entry.

tellows does not automatically collect data and names from your phone number. The database initially includes every possible telephone number. As soon as someone enters a number combination on tellows, it is recognized as a potential telephone number and exists with a unique URL.

Since your telephone number was entered there, it is available as a random combination of numbers in our database and will be used when you search again. Your number can therefore only be found if you have explicitly searched for it. It won't be displayed in search engines unless it has a certain amount of search requests or ratings. In addition, no data is stored for this number.

On the tellows, we offer people a forum to find and exchange telephone numbers. We have no information about which person is behind a phone number. The goal of our project is to protect people from unwanted calls. With the help of our tellows score, users can rate numbers and also have the option to leave a comment.

The phone number is assigned to a company at the earliest with a comment or a business entry. Company-related data - i.e. data of a legal person - are not protected by law insofar as they are publicly accessible. However, the comments can be deleted and checked if we receive a reason for deleting the respective comments. An examination is then carried out immediately.

Since over 1000 new comments are posted on tellows every day, we are grateful if we are informed of a possible breach of law in the comments so that we can investigate them. In consideration of the BGH judgment of August 17, 2011 (pen perfume), however, we ask for a reason to remove this comment.

You also have the opportunity to comment on the negative comments on tellows. This is placed on top of the others so that tellows users can be informed proactively.

If you feel that ratings or comments about your number is wrong or defamator and shall be removed, please get in touch with us and provide the following details in the contact form. Please be aware that we don't remove content without a reasonable explanation.
