First picture does not match actual product, second, I had my carrier signal become unavailable, due to this replacement . Switched back to my original one (only got the replacement cos' the usb port was bust on mine) , signal back on full strength. Conclusion? Poorly made antenna contacts.
Too bad I've changed every bit related to the antenna, including new sim, possible before testing the old port back.
There's cheaper replacements, went for this totally regret it now. Wish me luck with my next £2 pound one from eBay.
