Frequently Asked Questions
My MTN B310 only shows MTN SIM cards — can you unlock it?
Yes. MTN-locked B310 devices are our most commonly unlocked model. After unlocking, it will work with any carrier’s SIM card.
Should I buy V4 or V5?
Older B310/B315 models typically use V4. Newer firmware versions use V5. The easiest way to check: insert a non-MTN SIM — if it asks for 8 digits, buy V4. If 16 digits, buy V5.
Is the unlock permanent?
Yes. Permanent through firmware updates and factory resets.
Can I use external antennas?
Yes. Both B310 and B315 have 2x SMA external antenna ports. Highly recommended in rural areas with weak signal.
