Compatible package selected Review the added allowance, coverage, validity and published price. One purchase to follow Track the accepted order through its charge and fulfillment. Example balance and observation time. This preview does not quote a plan or buy a top-up. ## Show what the network has reported. Display remaining allowance with its observation time and package state. Keep a delayed update distinct from a zero balance, and show expiry independently from how much data appears to remain. ### One profile can hold multiple packages Explain which package covers the destination and when it can be used. Package ordering and stacking follow the service’s supported behavior. ### An alert that helps Connect allowance or expiry notices to the observation behind them. Give the customer a useful next step and avoid presenting a delayed network feed as a precise live spending control. ## Offer a top-up that belongs to this eSIM. Use the eligible offers for the allocated profile. Show the new allowance, coverage, price and validity rules before the customer approves an additional charge. ### Make the effective terms clear Explain whether the package starts immediately, waits behind another package or uses a different activation rule. A top-up does not automatically extend every existing allowance. ### Track the purchase through fulfillment Keep the accepted order and its financial result visible. If provisioning is still pending, let the customer follow the existing purchase rather than encouraging a second one. ## Keep repeat purchases under control. Define who can buy another package and what requires approval. For an employee program or automatic top-up, make the authorized amount, applicable offers and repeat limits explicit. ### Use an understandable approval Give the purchaser the relevant terms and total before committing. A notification about low allowance is useful information, not permission to charge. ### Review the outcome Connect each top-up to the profile, order and recorded charge. Investigate an allowance discrepancy through that history, including the freshness of the network report. ## Build with the right reference - [Usage and top-ups guide](/docs/guides/esim/usage-and-top-ups): Follow the setup, requirements and operational checks. - [Get started with eSIM](/products/esim/getting-started): Choose an offer and follow a controlled purchase-to-first-use journey. - [Plans and pricing](/products/esim/pricing): Review coverage, allowance, validity and the published terms. ## Usage and top-ups questions ### Is usage always real time? Usage timing depends on the network and service. Show the latest observation time and treat an unavailable update as missing information, not zero use. ### Can any package top up an existing eSIM? No. Use the compatible offers returned for that allocated profile. Coverage overlap alone does not establish compatibility. ### Does a top-up extend the current expiry date? The offer’s validity and stacking rules determine what happens. Present the effective terms of the new package before purchase. ### How should we prevent duplicate top-ups? Follow the existing order to its outcome when a response is uncertain. Use the documented request identity and recovery behavior for your integration instead of creating another purchase blindly. ## Connect the complete service - [eSIM installation](/products/esim/installation): Help customers install on their device and get connected with clear guidance. - [Travel eSIMs](/products/esim/travel): Bring destination data, installation and top-ups into your travel experience. - [Connectivity operations](/products/esim/operations): Bring orders, billing, network status and support into one service history. - [eSIM resource library](/products/esim/resources): Browse practical guides, explained answers and technical references. ## Give the next purchase clear terms.
