- Can I sell a broken or faulty Bf?
- Yes. Envirofone buys Sigma Bf devices in any condition — whether yours has a cracked screen, water damage, a faulty battery, or is completely non-working. Select "Faulty" as the condition above and we'll give you a fair price. The only devices we cannot accept are those reported lost or stolen.
- Where is the best place to sell my Bf in the UK?
- Envirofone is one of the most trusted places to sell your Bf in the UK. Since 2005, we've paid over £160 million to customers and recycled millions of devices. We offer competitive prices, free postage, same-day payment and no seller fees. Unlike marketplace listings or comparison sites, you sell directly to us — no middlemen, no waiting, and no risk of scams.
- What should I do before selling my Bf?
- Before sending your Sigma Bf, back up your data, sign out of your account (Apple ID for iPhones), disable Find My Device, and perform a factory reset. Remove your SIM card and any cases or accessories you want to keep. This protects your personal data and allows us to process your trade-in quickly.
- How long does it take to get paid for my Bf?
- We test your Sigma Bf on the day it arrives at our facility. Once it passes inspection, payment is processed the same day via bank transfer — or choose EnviroCash for a 7% bonus to spend on a refurbished device. Most customers receive their money within 3–5 days of accepting their quote, including postage time.
- Is it worth selling my Bf now?
- Yes — trade-in prices decrease over time as newer models launch, so selling sooner means getting more cash. Your Sigma Bf still holds strong value on the refurbished market. Lock in today's price with a 14-day price guarantee and sell before the value drops further.
