Simsima does not provide a truly unlimited data eSIM for Guyana; every plan it sells has a hard data limit. The only plans that use the word “Unlimited” in their name deliver 3 GB of high‑speed data each day and throttle speed to 1000 kbps after that amount is used.
For travelers who need more data, Simsima offers fixed data plans. A 20 GB bundle is valid for 365 days and is delivered via 5G, while a 10 GB plan is available for 30 days. Smaller options include a 5 GB bundle that can be used for 30 days or 60 days and, in the 60‑day version, the connection can also run on 5G and covers Guyana plus nearly 200 other countries.
Simsima does not provide an eSIM for Guyana that includes a phone number or SMS capability. The plans offered are data-only, so travelers cannot receive or send text messages or receive calls through a local number. However, the data connection can support voice and messaging apps such as WhatsApp, Telegram, and iMessage for calling and texting over the internet. Travelers should verify that these VoIP services are accessible in Guyana before purchasing, as local restrictions may affect usage.
Simsima offers 9 single‑country data plans for Guyana and 4 multi‑country plans that include Guyana. The single‑country offerings cover data caps ranging from 1 GB up to 20 GB, while the multi‑country options accommodate a similar range of data allowances but distribute them across several destinations.
The catalog contains both fixed‑data plans—where a set amount of data is delivered for a lump‑sum price (9 in total)—and daily‑cap plans, which allow a specified amount of data to be used each day (4 of these). Prices span from about $7.73 to nearly $182, giving consumers a broad selection to match their budget and usage needs.
