Your 'shield' is tiny! Cellphones are designed to connect with the network, hell, highwater, or pie pans notwithstanding. Use a much larger shield, or entirely encase the phone.
Here's an idea---wrap a phone up, and then open a tiny chink in the foil--show just HOW tiny a hole the phone needs to emit and connect. RF is like light--it will easily travel around small obstructions and pour through holes.
@thisirradiatedlife In a week, or so, we will complete experiments that will likely show that it is a VERY BAD IDEA to install a large smooth aluminum foil over a smart meter. We just completed a definitive test that proves that large smooth (ungrounded) aluminum foil reflects approximately 8dBm back to its source, assuming that the source. Please think about this carefully, because your RF meter does not have a histogram. Kudus for your courage..
@GustavoArnoldG Sorry, Gustavo, but we've been there, done that. Will share results at a later time. Not what you expect. With due respect, most standard "industrial" information is not validated by our instrumented tests. RF blocking is a complicated issue. That's why we do our own testing. Cheers, Rob
for Tv cable unions i use some paper then wrap in in tin foil to block the signal . it sometimes jams car remote systems for doors . you do need need to completely wrap the phone or use mess netting to stop the signal . Peace

Your aluminium foil is not connected to ground; this is the correct shielding technique,

Try wrapping foil completely around the cell phone and see how that works out.
