Using a .tel domain does not have a positive influence on being able to find a website, when compared to a normal gTLD or ccTLD.
The domain ending .tel is a so called sponsored top-level-domain (sTLD) and is actually not supposed to make a website available but to display the owner’s contact data.
If you want to create a commercial or private website you should choose a different domain ending from .tel.
Which top-level-domain (TLD) should I choose?
That is up to you to decide and depends on the type of website you have, as well as your visitors and your business model. If international SEO matters to you, you should at least be aware of the differences and possibilities between a gTLD and ccTLD.
