- Reader Jim reports that when his iPhone was not connecting to cellular network, he had some luck making his SIM card a little bit thicker by using a small piece of clear scotch magic tape. Adding it as one layer on the SIM card and another layer on the top of the SIM Card holder. This gave Jim longer lasting results but still is not perfect! But it’s a good place to start or at least try and see if it works for you!
