One advantage of modern phones is that when you miss a call, you usually see the caller’s number displayed.

It is different with’s reverse phone lookup engine. After installation, the app reads your own address book. The phone numbers are then processed and made available online. If you unintentionally find your number listed here, you can block the entry.

## Finding the mobile number: Who called?

Especially for telemarketing calls, a simple Google search often helps. Enter the respective number in the search field. In order for Google to use the exact phone number for the search query, you need to use a Google trick. To search for the exact number you entered, put the numbers in quotation marks. As an example, the search box would contain a number like “0151 9876543”. Tellows is a web service where numerous numbers are stored. Users can ask their own questions about specific mobile numbers. With the mentioned services, you can not only search for a mobile number, but also perform a reverse search for landline numbers.

## Reverse phone lookup options

* Enter the mobile number on the aforementioned websites to initiate the reverse phone lookup.
* However, many mobile phone owners do not agree with the possibility of being found through inverse search.
* Therefore, when performing a reverse phone lookup, you depend on the mobile number being listed in one of the mentioned directories.
When you are regularly called from an unknown number, it is recommended to visit the Tellows service. Here, you also have the option to find mobile numbers through reverse phone lookup. Tellows mainly lists telemarketers and other aggressive callers. The entries come from other telephone and mobile phone owners who post their experiences here. This way, you can quickly and easily determine if your mobile service provider wants to offer you a new contract with changed conditions or if the online store where you recently made a purchase wants to provide information through a call. Unlike a regular reverse phone lookup, Tellows provides personal user experiences and a risk assessment in case the number is associated with spam or a subscription trap. Of course, you can also simply enter the phone number into Google and hope that this number has been stored somewhere or has already been discussed on Tellows and similar platforms.
