Yallo prepaid eSIM was unusable from the start: I only had sporadic 3G signal (or "No Service"). I couldn't make calls, send SMS, or use data outside Wi-Fi from day one, as the SIM would only receive 3G — which shouldn't even exist anymore since 3G is fully switched off nationwide and repurposed for 4G/5G.I provided proof (Field Test screenshots, Sunrise app failures "Could not activate mobile data"), escalated multiple times, but their support sent repetitive irrelevant forms, they ignored the network fault, and they eventually deactivated the line with no warning or refund (number was never usable due to their issue not mine). Yallo are an extremely bad company that provides a slow and ineffective customer service. Avoid this company if you don't want to be scammed.
