Just so you know, cell phone signals are very low energy and this is why they aren’t penetrating your steel cans. An EMP on the other hand is a pulse of extremely high energy and is far more likely to penetrate the steel. You can’t say your electronics are safe from EMP just because they aren’t receiving their normal signal.
If you can get your hands on military grade electronics rather than commercial, you won’t need any sort of extra shielding as their circuitry is designed to withstand EMPs by having far thicker circuits and more/wider insulation between circuits. They’ve learned from when the last time the sun gave off an EMP.
Tin foil will block transmissions but not an EMP, if it were that easy they would seal electronics in shielding instead of making the circuitry resistant.

I would disregard all comments here, including my own, after reading this. Start at page 34 for guidelines on how to protect equipment. A microwave will serve as a faraday cage. You do want to limit length of circuitry. https://www.cisa.gov/sites/default/files/publications/19_0307_CISA_EMP-Protection-Resilience-Guidelines.pdf
