A used iPhone 11 can cover calls, messages, banking and family photos. Yet picking 64GB for its lower price can leave someone clearing storage every week. TECHBUY lists 64GB and 128GB versions; the sensible choice depends on the data you already carry and the condition of the exact phone you will receive.
Measure storage before comparing prices
Open storage settings on your current phone. If it is already near 50GB, a 64GB model leaves little headroom for photos, video, apps and updates. Someone recording family videos or keeping offline music may benefit from 128GB. Cloud storage does not remove the need for local app and download space.
Advertised capacity is not all available to you: the operating system and installed apps take some. Transfer a representative batch of photos, install your essential apps and see what remains.
Inspect the actual unit, not the listing photograph
Try front and rear cameras, microphone, speakers, charging, Wi-Fi, touch and face recognition. Read battery condition in Settings but do not treat a percentage as a promise of runtime; use the phone with your normal apps for a while.
Have the previous account signed out, confirm there is no activation lock and ask exactly what the warranty covers. For required banking or school apps, check that their current versions run on the iOS installed on this phone.
When is an iPhone 12 a better comparison?
Apple specifies a Liquid Retina HD LCD and A13 chip on iPhone 11. iPhone 12 has a Super Retina XDR OLED, A14 and 5G. If display quality or connectivity matters, place a used iPhone 12 alongside the 128GB iPhone 11 rather than automatically paying for more storage.
Match storage, battery condition, warranty and total price. A 64GB iPhone 12 will not solve full storage. If capacity is the real bottleneck, a sound 128GB iPhone 11 may serve you better than a newer but cramped phone.

Conclusion
Choose 128GB when photos, video and apps have already filled your present phone. A 64GB unit fits only when your usage is genuinely light and that unit is in good condition. Inspect the actual device, then consider iPhone 12 if OLED or 5G is worth the difference.
