Here’s some answers to our most popular business mobile questions.
Yes. Giant partners with all four of the UK’s major mobile operators – EE, Vodafone, O2 and Three. Giant’s site emphasises that you can “mix and match across carriers to get the best coverage for every site,” yet receive a single bill and have one account manager. The ability to select from multiple carriers means you can tailor coverage for each office or employee without juggling multiple providers.
For voice‑and‑data (V&D) SIMs, unlimited calls and texts are standard. Giant advertises “unlimited UK standard calls and texts”, so you don’t need to worry about running out of minutes. This approach is consistent with wider industry practice
Yes. In addition to plans with specific data allowances, Giant offers fairly priced unlimited data. Their site states there are “no confusing overages or hidden costs – enjoy unlimited business mobile data at fair, transparent rates,” designed for teams that need flexibility without usage caps. As with most operators, fair usage policies may apply to unlimited data plans, so it’s worth confirming any limits when you order.
Giant offers two categories of business SIMs:
Voice & data (V&D) SIMs – These include voice minutes, texts and data for smartphones. Plan options on the site show V&D SIMs with different data allowances (for example, 2 GB, 10 GB or unlimited data) and no set‑up fee.
Mobile broadband (MBB) or data‑only SIMs – These are designed for internet‑only use cases. Giant notes that data‑only SIMs are “ideal for routers, tablets, laptops, IoT devices and backup connections”. This matches the industry definition of mobile‑broadband SIMs: they provide high‑speed data for devices such as laptops and routers and are commonly used for temporary connectivity, pop‑up offices and consumer electronics
Yes. Giant highlights that it offers eSIMs for instant deployment, allowing you to provision new connections over the air without waiting for a physical SIM card. An eSIM is an embedded chip that can store multiple carrier profiles; mobile network operators can activate and manage it remotely using remote SIM provisioning. This makes it ideal for remote staff or rapid deployments because employees can download a profile and be connected immediately.
Managing a fleet of SIMs can become complex as your team grows. Giant provides a SIM Estate Management portal: a self‑service, scalable interface that lets you manage all your employees’ SIM cards in one place. Through this portal you can monitor usage, apply restrictions, order replacements and keep track of device inventory. Businesses with many mobile users benefit from a unified dashboard instead of dealing with individual accounts for each SIM.
Yes. Keeping your number when switching provider is called “porting.” According to Ofcom, to switch and keep your old number you need to request a Porting Authorisation Code (PAC) from your current provider and then give it to your new provider.
