I am trying install this > **[mtcextendee/mautic-international-phone-input-bundle](https://github.com/mtcextendee/mautic-international-phone-input-bundle)** > > Integration form field https://intl-tel-input.com/ for Mautic But it is returning error: Problem 1 - mtcextendee/mautic-international-phone-input-bundle[1.1.0, …, 1.1.3] require mautic/composer-plugin ^1.0 → satisfiable by mautic/composer-plugin[1.0.0, 1.0.1]. - mautic/composer-plugin[1.0.0, …, 1.0.1] require composer-plugin-api ^1.0 → found composer-plugin-api[2.0.0] but it does not match the constraint. - Root composer.json requires mtcextendee/mautic-international-phone-input-bundle ^1.1 → satisfiable by mtcextendee/mautic-international-phone-input-bundle[1.1.0, 1.1.1, 1.1.2, 1.1.3]. You are using Composer 2, which some of your plugins seem to be incompatible with. Make sure you update your plugins or report a plugin-issue to ask them to support Composer 2. I tried install manually. but didn’t work. How to solve? ---

Agree that this plug-in has served me well. I have a few others that we use that would need to be updated for Mautic 3. ---

Hi, There is international phone validation as a default: ![image](https://us1.discourse-cdn.com/flex020/uploads/mautic/original/2X/e/e14f14320ae60c742c644772cb3380641b765547.png) The reason why features not getting into the core is NOT because the evil lizard-men decide to remove it, but because there are resources missing to accomplish that. If you can update this to M3, plz do so 🙂 Joey ---

I Know there is a “validate as international format” option. But here in my country the people have problems to insert +55 after the number. The major of the people doesn’t know about international prefix. To use geolocalization to insert the international code resolve this problem. Thanks a lot ---

Hi, as this is a custom plugin, you can always request the creator to update it. At the same time, you can also use the validation error text to tell them: HEY, YOU NEED TO PUT +55 IN FRONT AS THIS IS INTERNATIONAL FORMAT! OBRIGADO! Joey
