Yes, I know, not so “mustachian”. But from time to time it has to be done. As a Yallo customer, some time ago I was informed about 123mobile.ch. Quite often they have so called Crazy Deals, with really good prices. I already bought one phone using them (especially that I got additional voucher of 100 CHF as a Yallo user). Quality of service was very good (nice website, quick delivery). So, for sure I can recommend at least subscribing to their newsletter about Crazy Deals.
Today I got another message with personal link to 50 CHF voucher valid until end of December, but I don’t want to post it here (I’m not sure if I’m not braking forum rules even mentioning this here, if yes, please let me know, I’ll remove it). If interested, please contact me directly. If you use it, I would get 50 CHF too.
