$49 – 28 day Prepaid SIM + eSIM: $6.50 $13
Also available:
75GB for $13, unsure if cashback applies. It's the '$35' plan though an 'online only offer'. Doesn't include unlimited data weekends.
$35 – 28 day Prepaid SIM + eSIM: $5.50 may apply, making it the better deal.
No profit for this one but thought it's worth posting if someone needs some cheap quick data for a month.
Could be good to stack with Perplexity Pro offer. Unsure if it applies to 28 day SIMs though
