Firsty inside Grab is built for travellers who already use Grab for rides and food. Purchases run on Firsty Telco (our modern travel network stack). You can buy daily passes (including First Class with unlimited data) and gigabyte bundles — in the Grab flow those data packs are labelled Pay as you go. Each product has its own validity rules; always confirm on the checkout summary before you pay.
Grab’s Firsty experience is data only — there is no Firsty in‑app calling and no monthly subscription checkout in the Grab mini‑app. Anything not shown there (for example monthly plans or Firsty calling) simply is not part of this Grab journey — use the plans and payment options inside Grab for your trip.
Your purchases can use GrabPay, cards, and other methods Grab supports. Credits you already hold in your Firsty Wallet may also be available at checkout when the Firsty flow offers wallet pay — see Understanding Firsty Credits for how wallet balance works today (plan checkout; not for burning Firsty Free; no ads‑for‑credits; legacy Flex for a small cohort until migration).
What you can buy in Grab today
1. Daily plan (day pass) — including First Class
Best when you want unlimited data for a set number of days you choose in the flow (for example 1, 7, or 15 days — options depend on region and catalogue).
You pick how many days.
If you already have an active daily pass of the same product line and you buy more days, Firsty extends your end date by those extra days (you should not lose unused paid days when stacking the same line).
Pause / Resume may appear for some daily products when your trip changes — use in‑app controls when offered.
First Class is unlimited data for the days you buy — you are not cut off after a fixed GB cap.
Each calendar day you get about 5 GB at high speed. After that, all of your traffic for the rest of that day runs at reduced speed until the next day gives you a fresh high‑speed bucket. Speeds and reset timing follow what checkout and in‑app help show for your build and region.
Essential apps: You also get full access to essential apps (which apps qualify depends on the product in your region). That follows separate rules from the 5 GB high‑speed / then reduced speed behaviour for all your other traffic — keep the two ideas apart.
2. Pay as you go (gigabyte data packs)
In Grab, fixed‑GB packs appear under Pay as you go (same product family we elsewhere call gigabyte bundles). Best when you want a set amount of data with a clear expiry.
Sizes you can buy: 1, 3, 5, 10, or 20 GB.
Discounts on the pack price (typical catalogue):
5 GB and 10 GB — 10% off
20 GB — 15% off
(1 GB and 3 GB are usually at the base price — confirm on the price line before you pay.)
Validity: Pay as you go packs are valid for 30 days from the rules shown at purchase (each pack has its own end date).
If you buy a second pack while the first is still active, the second pack still gets its own 30‑day window from its activation rules — it does not “stack onto” the first pack’s expiry date. You may see two different expiry dates for two active packs.
You may hold several Pay as you go packs at the same time. They are separate entitlements behind the scenes; each pack keeps its own clock until used or expired.
Buying a new pack does not reset the timer on an old pack.
If sizes, discounts, or day counts differ from this article, trust what Grab + Firsty show at purchase time.
3. First Class (daily) and Pay as you go together
You can have an active First Class daily pass and one or more Pay as you go packs at the same time.
Tip: When you have both, using your Pay as you go GB first (instead of leaning on the unlimited line’s high‑speed slice) is usually the better experience — you keep more of your daily high‑speed allowance free for when you want it.
Seeing both allowances: On the relevant Firsty screen inside Grab, swipe left to right — a second view should show both your day‑based entitlement and your GB packs (wording varies by locale).
How to purchase (high level)
Open Firsty from the Grab mini‑program / integration you use.
Choose Daily (day pass / First Class) or Pay as you go / gigabytes (wording may vary slightly by locale).
Pick destination or coverage as guided.
Review price, discounts, validity, and what is included on the summary screen.
Pay with GrabPay or other linked methods, or use Firsty Wallet / Credits if that payment tile is shown.
To review day passes and GB packs together after purchase, use the left‑to‑right swipe on the plan / usage screen when the app offers it (see §3 above).
After you pay — install your eSIM (stay in Grab)
Your purchase is tied to the Firsty flow inside Grab, not the standalone Firsty app.
Stay in (or reopen) the Grab app
All Services → Firsty
Follow the prompts to install or open your eSIM / plan screen
Complete any phone Settings steps your device shows for eSIM install
If install options are missing after payment, use Support from this Grab → Firsty path and mention you bought through Grab.
Firsty Credits and Grab
Credits = wallet balance used at checkout for daily passes and Pay as you go (gigabyte) packs in Grab. Monthly subscriptions are not sold in the Grab mini‑app.
Not used to replace Firsty Free (ads) or to earn more balance by watching ads.
Flex: new Grab users are not sold Flex; some existing Grab users may still be on Flex with legacy wallet rules until we migrate them — follow what their app shows.
100% cashback (new users)
Some users still see a 100% cashback style offer on a first qualifying purchase. When it applies, the cash value of that promotion is credited back to your Firsty Wallet according to the rules on the banner — treat it as a wallet top‑up for your next eligible checkout, not as a second free data entitlement unless the banner explicitly says so.
Dynamic pricing
Prices and taxes can change by country, currency, and partner promotions. Always confirm the final amount in Grab before you confirm payment.
“Always online” for Grab
Even when your travel data allowance is empty, Grab may still let you use Grab services (rides, food, etc.) on their side depending on region and your Grab account — that behaviour is between you and Grab; it is not a promise that Firsty data stays unlimited without a plan.
Expiry cheat sheet (support + customers)
Purchase type | What expires? | Stacking behaviour (typical) |
Daily pass | The paid day window for that pass | More days on the same active daily line extend the end date |
Pay as you go (GB pack) | Each pack’s validity window (typically 30 days where shown) | New pack = new window from its own rules; does not extend old packs — two packs ⇒ two expiry dates |
Wallet balance | Does not auto‑expire like a single GB pack | Stays until you spend it on eligible Grab checkout (calling does not apply in Grab) |
Need help?
Use Support from your Firsty flow inside Grab and mention Grab, what you bought (daily / First Class vs Pay as you go), and the date shown on the receipt / in‑app order if something does not match what you expected.
