After doing some research and reading through articles on this claim, it seems to be somewhat true that Ukranian Intelligence Services tapped the mobile phone of the Hungarian Foreign Minister Peter Szijjarto. Through one of the sources that I found, it states that a joint media investigation had published a report revealing leaked information from a phone call that occurred between Peter Szijjarto and Sergei Lavrov, the Russian Minister of Foreign Affairs. The article gives direct quotes from Peter Szijjarto and how he felt regarding the leaking of his private phone call with Lavrov. Szijjarto did not deny the phone call that had taken place, but he mentioned that his calls were intercepted. From another source that I read through, it states that Szijjarto came face to face with an unnamed Hungarian journalist, who was likely the one that wiretapped Szijjarto's phone call.
The source below helped me determine whether it was true that Peter Szijjarto's phone was tapped by Ukranian Intelligence Services specifically. Through this article, I was able to read quotes given by Szijjarto talking about the incident and learn how he personally felt about it.

Through the source below, I learned that Peter Szijjarto had accused "certain intelligence services" of working with a Hungarian journalist, and wiretapping his phone conversations to attempt to undermine Prime Minister Viktor Orban.

The evidence that supports that the claim is true is the quotes given by Szijjarto from the articles. "It is a huge scandal... that foreign secret services were continuously wiretapping my phone calls and that these foreign secret services have now made these phone calls public one-and-a-half weeks before the Hungarian parliamentary election." This quote demonstrates that Szjjarto experienced the interception of his calls. This was because of a Hungarian journalist that he had interacted with. The Washington Examiner article mentions, "Szijjarto accused “certain foreign intelligence services,” working with an unnamed Hungarian journalist, of having “wiretapped” his phone conversations in an attempt to undermine Prime Minister Viktor Orban’s government."
