MobiBLOCK — Device Blocking and Asset Protection for Businesses
When a valuable phone goes missing, is stolen or becomes the subject of a disputed return, paperwork alone may not be enough. MobiBLOCK gives your business a practical way to protect its interest in the device itself.
Record an ownership or financial interest against a device’s IMEI from just 10p per device. For eligible lost or stolen handsets, submit a request for blocking across participating UK mobile networks for £1 per device. Removal is free once the matter is resolved.
Whether you sell phones online, manage rental or leased handsets, finance devices or process used stock, MobiBLOCK helps you flag interests, respond to qualifying incidents and maintain a clearer evidence trail — without treating every disputed device as a network-blocking case.
MobiBLOCK Pricing — Protection from Pennies per Device
Two different ways to protect your business, with straightforward per-device pricing.
1,000 General List markers at 10p each = £100. A simple extra step when your business handles valuable devices at scale.
Network blocking is subject to eligibility and participating-network rules. An interest marker does not itself block a handset or guarantee recovery. Please enquire about applicable VAT and terms.

What Is MobiBLOCK?
A straightforward way to record device interests, request eligible network blocking and protect valuable mobile stock.
MobiBLOCK is designed for organisations that sell, rent, lease, finance, process or insure mobile devices. These businesses often carry financial or operational risk when a device is stolen, retained, resold or disputed.
Instead of relying solely on marketplace decisions, courier investigations or customer cooperation, MobiBLOCK provides an IMEI-level record and, where a device qualifies, a route to network blocking. This can help deter misuse and make relevant device status more visible to participating trade businesses.
This is especially valuable for companies handling large volumes of smartphones, tablets and connected devices. Consequently, even a relatively small level of fraud, theft or non-return can create meaningful losses.
How MobiBLOCK Works
Two distinct options: record an IMEI interest from 10p, or request eligible UK network blocking for £1.
IMEI-Based Blocking
For £1 per eligible lost or stolen device, a business can submit an IMEI for blocking on participating UK mobile networks. Where applied, the block restricts cellular access and can reduce the handset’s usefulness and resale appeal.
In turn, this gives businesses a stronger deterrent when a device is stolen, fraudulently claimed, kept after sale or not returned after rental.
Finance and Rental Flagging
From 10p per device, MobiBLOCK can flag an ownership or financial interest in a phone that remains under finance, rental or lease agreements. Participating businesses checking that IMEI can then see that an active interest may exist.
This means buyers, recyclers, retailers and processing teams can investigate the device before they purchase or process it.
Written Evidence Trail
Every action can create a written record. In addition, that record can support marketplace disputes, insurance claims, internal reviews, police reports and legal escalation where required.

Stop Marketplace Device Fraud
A clearer device-level record to support disputed delivery, return and refund claims.
False Delivery and Return Claims
Marketplace fraud affects businesses that sell devices through platforms such as eBay, Amazon, Back Market and Facebook Marketplace. For example, a buyer may claim that a device never arrived or was returned even when tracking evidence suggests otherwise.
MobiBLOCK gives sellers a more structured response. First, review the evidence and confirm your right to report the device. Where appropriate, send a factual written notice explaining that an eligible device may be flagged or submitted for blocking after the required checks.
In many cases, that warning can help clarify the situation. For instance, the buyer may confirm possession, withdraw the claim or provide more information. As a result, the seller gains clearer evidence for the marketplace dispute process.
Marketplace Fraud Protection Process
- 1First, the buyer claims that a device was not received or was returned.
- 2Next, the seller reviews delivery records, courier tracking, marketplace messages and return evidence.
- 3If the evidence supports it, the seller sends a written warning about possible reporting, blocking or flagging.
- 4Afterwards, the buyer may confirm possession, withdraw the claim or provide more information.
- 5Finally, the seller keeps and submits the evidence during the marketplace dispute process.
Protect Rental and Leased Device Fleets
Reduce the risk and value of devices that customers do not return.
Companies that rent or lease smartphones, tablets and connected devices face ongoing risk. For example, devices may be lost, stolen, kept after the rental period or resold without permission.
At just 10p per device, businesses can record relevant ownership or financial interests against their rental fleet. Where a handset is eligible for network blocking, MobiBLOCK also provides a separate £1 request route. Not every late return qualifies for a network block.
In addition, MobiBLOCK can support phone fleets, tablet fleets, loan devices, staff devices, student devices, event devices and leased handsets.
Safeguard Devices Under Finance
Flag devices that remain under active finance agreements.
When a customer finances a device, the lender may retain a financial interest in that device until the agreement ends. However, if the customer tries to sell the device early, a buyer or recycler may not know that finance still applies.
MobiBLOCK can flag the active finance interest against the device’s IMEI from 10p, so participating device checks can reveal that status before purchase, recycling or resale.
As a result, finance providers gain greater visibility and can strengthen device-status records across the wider mobile-device market.

Frequently Asked Questions
Clear answers about how MobiBLOCK helps businesses block, flag and protect mobile devices.
How do I block a stolen or lost mobile phone?
With MobiBLOCK, a business can submit the device’s IMEI number for blocking or flagging. As a result, the device can be restricted from participating mobile networks.
How much does MobiBLOCK cost?
Recording an ownership or financial interest on the General List starts from 10p per device. An eligible lost or stolen handset can be submitted for UK network blocking for £1 per device. Removing a marker or block once resolved is free. Ask MobiCode about eligibility, applicable VAT and terms.
Can MobiBLOCK help with marketplace fraud?
Yes. MobiBLOCK helps sellers respond to false “not received” and “returned” claims. In addition, it helps sellers create a clearer evidence trail before they escalate a dispute.
Can I flag a device as being under finance?
Yes. MobiBLOCK can flag a device as subject to an active finance agreement. Therefore, buyers, recyclers and retailers can see that a financial interest may exist.
Can rental companies use MobiBLOCK?
Yes. Rental and leasing companies can use MobiBLOCK to protect unreturned devices. As a result, customers have less incentive to keep or resell rented devices.
How does MobiBLOCK integrate with MobiCHECK?
MobiCHECK can show devices that MobiBLOCK blocks or flags. Consequently, businesses can identify active blocks, warnings or finance and rental interests during device checks.
How do existing MobiCode customers request MobiBLOCK access?
Existing customers can request access directly through the Blocklist Access page in MobiCode Server. Therefore, they do not need to submit a separate general enquiry.
