SIM swap - pseudoscience?

Just a quick question for some of the more technically knowledgeable people on here... I can't help but notice that 'sim swaps' are recommended on these forums for all manner of ailments, but from my experience most of these suggestions seem to be overkill. I don't think that after 96 years of using gsm sims (exaggeration), not even when I worked in a job maintaining a fleet of mobile gsm modems in the early noughties, that I've ever experienced a sim fault, not even anecdotally from friends & colleagues.

Are these SIM swap suggestions legit? Do dodgy sims really cause signal problems rather than being hard failures?

Maybe they are just rubbish sim cards these days but they do fail.... quite often unfortunately.

@MI5  A query please.

Back in the day we only had one sim type. Is is possible that we have more faults now due to having Mini, micro and nano sim...

As you know I am not at all technical but it seems 'coincidental' that the problems are increasing when we have more types available?Smiley Frustrated

Anything's possible....
Along with cost cutting and cheap manufacturing etc.

I can remember the days you had to pay £9.99 if you blocked a sim and had to order a new one. Now they are ten a penny. Cheaper manufacture hence cheaper quality methinks!

See...I am not at all technical...but nothing like a bit of logicSmiley Very Happy

Facts are facts though, (according to many posts on this forum)

Frequently a sim swap does seem to work to correct some problems......

Let's be honest it's like everything over the years it's all lost it's quality now these things are so mass produced and cheaply made

Hi


I think it's also because people used to own one phone but now either people have a couple of devices or switch handsets / upgrade more often the act of taking a sim in and out of the sim tray in the device can cause more wear and tear.

This is an interesting discussion. Out of everyone involved in this thread, have you noticed a clear decline in SIM quality over the years?

With the advent of microsims and nanosims, they are obviously smaller, thinner and more prone to develop faults. Along with mass production and cheaper materials there is bound to be a noticeable difference in the number of simcard failures but bear in mind the vast numbers of smartphones out there compared to 4-5 years ago.
