| Feb 4 at 3:01 | comment | added | Math Keeps Me Busy | Someone else may have a better idea. When I was young I had a phonograph amplifier with the same problem you are experiencing, and I attached a wire from a water pipe to the amplifier to ground it. It was a hack, and really don't know what else to say. You might try buying a more expensive "linear" power supply with a transformer, but that may not be in your budget, and it may not fix the problem either, if you don't have a ground. If you do have a plug with a ground, you could try ground with amazon.com/StaticTek-Adapter-Universal-Connection-Unbreakable/… | |

| Feb 4 at 2:04 | comment | added | Math Keeps Me Busy | That looks like a US plug. Do you live in the US or in a country that has grounded recepticles? | |
| Feb 4 at 1:58 | comment | added | Mohamed Essam | This is the power source i am using adapter . yes it is just two prongs but here we don't have three prongs at all. and yes of course the module has GND pin this is the module i am using sim800l. can i simulate the finger touch by connecting gnd with the module's body for example? | |
