Do you really need a second SIM card in your smartphone?
A year ago and earlier, when I was a subscriber of the MTS operator, the presence of two SIM cards in a smartphone seemed to me a very important option. Why? It's just that MTS in Moscow has a lot of 'empty' places with slow or no internet. When I inserted the second Megafon SIM card for the first time and saw that there was quite a working 3G at the bottom of the orange branch, it was a big revelation for me. Before that, I was sure that all operators have bad Internet in the metro, and periodic 'empty zones' are also the norm. In general, I needed two SIM cards exclusively for using the mobile Internet from Megafon (this was before the abolition of mobile slavery). Now, using Megafon, I cannot think of a scenario for using a second SIM card. Work and personal number? What for? Mobile Internet? So now you can choose an operator with the best internet. Roaming? Too rare. In general, for me now, two SIM cards are not a particularly necessary thing.
And now a question for you, dear readers: do you need support for two SIM-cards in a smartphone?
