How do you call the prospects abroad?

Hi Makers, Our team is mostly based in Poland, but we're actively looking for ways to teleprospect in other countries (in the EU and the UK). However, it's quite tricky and uncomfortable to use the average SIM with the local number. We're a small team expecting to get a quote for 2-3 people. What services can you recommend for buying a virtual number for different locations and a democratic price? So far, I've seen a lot of scammy offers.
