The first telephone was installed in the district office of Tarutino in 1878. Teplitz received its telephone in 1909. The community chancellery of Alt-Posttal received theirs in 1923. It is not clear when the other villages were connected. The community chancellery of Krasna had a phone later, but as far as is documented, there were no private phone lines in the village.
Making phone calls was still a problem during the Resettlement as some reports of the resettlement community document show.
