Enterprise tier

Pay-as-you-go eSIM, billed per megabyte

Stop paying for data your customers never use. Run your eSIMs from your own pool on the network, design your own coverage and packages, and pay only for the megabytes actually consumed — the way operators buy from each other.

Is pay-as-you-go right for you?

Yes, if you run

5,000+ active SIMs / month

  • You resell eSIMs and carry unused allowance as a cost
  • You want your own coverage zones and package design
  • You need usage and cost per SIM, country and operator
  • You can hold a working balance with us

Not yet — use prepaid packages

Under 5,000 SIMs / month

Below that volume prepaid packages are almost always cheaper and simpler. Package pricing carries a volume discount a per-megabyte rate cannot match at low volume, and you avoid holding a float. We would rather tell you that than sell you the wrong tier.

Everything you need to run the fleet

Nine areas of the dashboard, and what each one is actually for. Everything on the business plan is included — these are the controls that only start to matter once you are running a fleet rather than buying packages.

Know what you are spending, before the invoice

The overview answers the only question that matters on a Monday morning: how much is this costing me and how long does my balance last.

  • Live balance read from the network, not a cached figure
  • Burn rate and projected runway in days, so a top-up is planned not panicked
  • Month-to-date spend and a daily usage chart
  • Your most expensive destinations ranked, so you know where to renegotiate

Run a fleet, not a spreadsheet

Every SIM you own in one list, searchable the way you actually think about them.

  • Search by ICCID, IMSI, MSISDN or your own label
  • Label each SIM and assign it to a person or department
  • Per-SIM spend visible in the list, so the expensive ones surface themselves
  • Bulk suspend, resume, enable or disable data across a selection
  • Import a CSV to label a batch in one go

Attribute every megabyte

Usage broken down far enough to price by destination instead of guessing an average.

  • Day by day, 7 / 14 / 30-day windows per SIM
  • By country, and by operator within each country
  • By department or assigned owner for internal recharging
  • CSV export for your own billing and reconciliation

Answer “it is not working” in seconds

The network records for any SIM, in plain language. Support stops being guesswork.

  • Roaming registration (MAP), LTE attach (S6a) and charging (Gy) events
  • Which operator refused, and the exact reason code
  • Last seen, last network, RAT type, APN and device IMEI
  • The eSIM profile itself: QR, activation code, PIN and PUK, and whether it was ever installed

Stop a bad month before it happens

Rates differ more than tenfold between operators in the same country, so a data cap in gigabytes does not bound your cost. These do.

  • Per-SIM monthly spend caps, in currency not gigabytes
  • Account-wide cap that switches data off when reached
  • Low balance alerts by email at a threshold you set
  • Automatic stop at zero balance, restored the moment you top up

Control the SIM on the network

Changes apply upstream immediately, not at the next billing cycle.

  • Throughput cap per SIM, with presets or an exact kbit/s figure
  • Switch data, outgoing calls, incoming calls and SMS independently
  • Suspend and resume without losing the profile
  • Send an SMS to a SIM from the dashboard

Design the product you sell

Self-service mode. Build coverage and packages nobody else can list.

  • Pick the exact countries and operators in a coverage zone
  • Set data, validity, voice and SMS allowances per package
  • Fair-usage throttling in up to four steps
  • Auto-renewing packages with your own renewal rules

See what you are actually buying

The full rate sheet, per operator, so nothing about your cost base is a mystery.

  • Data, voice and SMS rates per operator, per country
  • TADIG codes and MCC-MNC for every network
  • 4G, 5G and VoLTE support flagged per operator
  • Rates shown per sponsor, because the same operator is resold at two prices

Bring your team in

More than one person runs a fleet this size.

  • Invite colleagues by email
  • Owner, admin and viewer roles
  • Viewers see everything and change nothing
  • Every balance movement recorded against who made it

Two ways to run it

Managed

You use our coverage and our packages; we handle the setup. Your SIMs still come from your own pool and usage still bills per megabyte against your balance — you simply do not have to design the product.

Self-service

You build your own coverage zones and package templates and sell them under your own names. Your API returns your packages, not ours. For resellers who want a product nobody else can list.

Pay-as-you-go eSIM: common questions

What is a pay-as-you-go eSIM?

You are billed for the data your SIMs actually use, per megabyte, against a balance you hold with us. There is no package to buy up front and nothing expires unused. It is the model mobile operators use with each other, offered to high-volume eSIM resellers and enterprises.

How many SIMs do I need for pay-as-you-go to make sense?

Around 5,000 active SIMs a month. Below that, prepaid packages are almost always cheaper and simpler: package pricing carries a volume discount that a per-megabyte rate cannot match at low volume, and you avoid holding a float. We will tell you if you are better off on packages.

What happens to data my customers do not use?

Nothing is wasted. On a prepaid package you pay for 10 GB whether 2 GB or 10 GB is used. On pay-as-you-go you are charged for the 2 GB. For resellers this is usually where the margin is: unused allowance stops being a cost you absorb.

Do I get my own SIM pool?

Yes. Your eSIMs live in your own account on the network, not in a shared pool. Your fleet, your usage and your balance describe only your business, and stock you buy stays yours.

Can I build my own packages?

In self-service mode you design your own coverage zones and package templates - which countries and operators, how much data, how long - and sell them under your own product names. In managed mode you use our coverage and packages and we handle the setup.

What happens when my balance runs out?

Data is switched off automatically across your SIMs and restored as soon as you top up. Calls and SMS keep working. You get a low balance warning by email before it happens, at a threshold you choose.

Does my existing API integration change?

No. Same endpoints, same authentication, same field names. Orders draw from your own pool and usage bills against your balance instead of a prepaid wallet, but the integration you already built keeps working.

Not sure whether pay-as-you-go beats packages for you?

Bring your monthly SIM count and the destinations you sell most. We will run the numbers against both tiers and tell you which one costs you less — including when that answer is packages.
