Who I have the same questioned this topic

Just picked up 2 NEW iphone 7s and transferred from another carrier with no issues prior . Hers  allows short code texts mine does not. On phone 50 minutes with tech support  still not resolved . Also checked with financial institution and no issues on there end going through all settings.  I transferred from an iphone 6 today and no issues including just before we changed over phones. Now new one nothing but problems receiving codes.

Tech claims he saw problem and it was fixed for both phones now? So whats up Verizon  still not working.
