Businesses often stay with an underperforming mobile provider for longer than they'd like, simply because switching feels like it will be disruptive. In practice, moving business mobile provider is far more straightforward than most people expect, and it doesn't mean losing your numbers or facing a gap in service. It's a switch we manage regularly for businesses across Bristol and the wider South West.
This guide walks through exactly how switching works, what it costs, and what to check before you commit to moving your business mobiles to a new provider.
How Number Porting Works
The process of moving your existing mobile numbers to a new provider is called porting. Your new provider requests a Porting Authorisation Code, or PAC code, from your current network for each number you're moving. A PAC code is free, and it's typically sent to you by text within minutes of requesting it.
Once your new provider has the PAC code for each number, they submit the porting request directly with your current network on your behalf. Your existing line stays active until the port completes, so there's no gap in service, calls to your number simply start being routed through the new provider once the switch goes live. Most businesses notice nothing beyond a brief reconnection, and porting typically completes within a single working day.
What It Costs to Switch
PAC codes themselves are always free and take minutes to request by text, whatever provider issues them. The cost to actually watch for is any early termination charge written into your current contract if you're switching before your renewal date. This is worth checking before you start the process rather than after, since a good new provider can often time the switch to avoid, or at least minimise, those charges.
Steps to Switch Business Mobile Provider
1. Review your current agreement.
Check your contract end date and any early termination terms before starting the process, so you know exactly what, if anything, switching early will cost.
2. Get a quote from a new provider.
A good business mobile provider will look at your current usage, coverage needs and any pain points with your existing setup before recommending a network and tariff, rather than simply matching your current spend.
3. Request PAC codes
Text PAC to 65075 for each number you're moving, or have your current provider issue them, then pass these codes to your new provider.
4. Let your new provider handle porting
From here, a good provider manages the entire process with your outgoing network directly, so you don't need to chase anything yourself.
5. New SIMs, and handsets if needed, are provisioned
Everything should be set up and tested before your existing agreement runs out. If you're keeping current handsets, this is largely a SIM swap. If you're taking new devices too, they can typically be pre-configured and ready to hand out from day one.
What to Check Before You Switch
- Your contract end date. So the switch can be timed to avoid, or at least minimise, early termination charges.
- Which numbers need porting. And whether any are tied into a bundled contract with your current provider that affects the process.
- Handset requirements. Whether existing handsets are being kept, or new ones are needed alongside the new SIMs.
- Timing across the team. Porting several numbers at once needs coordinating properly, so nobody on the team loses service mid-switch.
- What happens to any shared data or account features. Pooled data, kit funds or bespoke tariffs on your current account don't automatically carry over, so it's worth confirming what your new account will offer before you commit.
What Your Team Actually Needs to Do
Very little, in most cases. Once porting is confirmed, employees generally notice nothing beyond their phone briefly reconnecting to the new network. There's no need to notify contacts of a new number, no saved details to update anywhere, and no requirement to change handsets unless the business chooses to.
Switching Provider as a Bristol or South West Business
As a local provider based in Clevedon, we handle number porting on-site or remotely for businesses across Bristol and North Somerset, and manage the same process for teams further out across the South West and M4 corridor. Being local means we can be on hand quickly if anything needs sorting out during the switch, rather than a business having to wait in a call queue with a national provider while their team is mid-move.
Switching provider can feel like a bigger job than it actually is. With PAC codes handling the number transfer and a good provider managing the process end to end, most businesses find the whole thing takes far less time and effort than putting it off for another year.
Bytes Digital manages the entire porting process for businesses moving their business mobiles across to us, handling the request directly with the outgoing provider for businesses across Bristol and the South West.
Frequently Asked Questions
How long does it take to switch business mobile provider?
Porting itself typically completes within a working day once PAC codes have been submitted. Allow a little longer either side for reviewing your current contract and getting new SIMs or handsets ready before the switch.
Will I lose my number if I switch?
No. Porting your number is the whole point of a PAC code, your existing number transfers across and stays the same, so clients and contacts can keep reaching you without any change on their end.
Can I switch mid-contract?
Yes, though you may face an early termination charge from your current provider depending on your contract terms. It's worth checking your agreement and, ideally, discussing timing with your new provider before switching mid-contract.
What is a PAC code?
A PAC code, or Porting Authorisation Code, is a free code from your current network that authorises your number to be transferred to a new provider. It's requested by text and normally arrives within minutes.
