Learn French: D'abord, je ne reçois plus rien sur mon smartphone. - First, I don't receive anything on my smartphone anymore.

When you use negative words like plus (anymore/no longer) or rien (nothing/anything), they replace pas. You never use pas together with them. So the combination ne ... plus rien literally means "not anymore anything".

Does the order of plus and rien matter here?

Yes, the order is strict. When combining negative words, adverbs of time like plus (anymore) or jamais (never) always come before negative pronouns like rien (nothing) or personne (nobody). So it must be ne ... plus rien, never the other way around.

Where would plus rien go if this sentence were in the past tense (passé composé)?

Both plus and rien are short negative words, so they would both wrap around the helping verb, going directly before the past participle. It would look like this: Je n'ai plus rien reçu (I didn't receive anything anymore).

What is the infinitive verb for reçois and why does it have a cedilla (ç)?

It comes from the irregular verb recevoir (to receive). The cedilla (ç) is added under the letter c to keep the soft "s" sound when it is followed by the letter "o" or "a". Without it, the word would be pronounced with a hard "k" sound.
