eSIMCard does not provide a truly unlimited data eSIM for Guatemala. Although several plans have “Unlimited” in their names, each plan contains a capped data allowance (typically 1GB or 2GB, or 1GB per day) and specifies a reduced speed once the cap is reached (500 kbps or 2000 kbps).  
For travelers who need more data without the speed throttling, eSIMCard offers fixed‑data options. Examples include a 25GB plan valid for 30 days ($164.18 USD), a 20GB plan for 30 days ($45.74 USD), and a 100GB plan for 180 days ($478.46 USD). These plans provide unthrottled high‑speed data throughout the validity period and can be more cost‑effective than the capped unlimited plans when large data usage is required.
