Sonic and AT&T Recap

Family Sitting on Couch with TV Remote Smiling

Sonic is a great balance of price and speed, but it does not offer the same variety of options as AT&T. Depending on your household needs, consider which provider is best for your lifestyle.

Pricing

While AT&T has a low introductory price of $49.99/mo. for internet service, you should expect to see substantial price increases after the 12-month promotional period. This is okay for those who don’t mind switching between providers after this time. However, if you want to stick with one provider that offers consistent pricing on all plans, Sonic is the way to go.

Speed

Both Sonic and AT&T offer competitive speeds for DSL and fiber internet. Sonic leads by a small margin with speeds of up to 1 Gbps compared to AT&T internet speeds of up to 940 Mbps. If you live in an area where both providers are available, Sonic is the best option for streaming, gaming, and multi-device connectivity.

Internet + TV Bundles

Since Sonic only provides internet and phone services, AT&T is your best option when it comes to internet and TV bundle deals. Owning DISH, AT&T offers 330+ channels and about 5,000 integrated apps for whole-home entertainment.

Availability

Unless you live in California, it’s more likely that AT&T is the top provider in your area. Available in 21 states to over 25 million people AT&T is widely accessible and offers competitive pricing and plans.

Customer Satisfaction

While both providers rank high in this category, Sonic is one step ahead of AT&T. Although AT&T is widely available, Sonic offers genuine local customer service that results in personalized care and high customer satisfaction. If you value direct support, Sonic is your best choice.

Making the final decision on which provider to go with is always a leap of faith in the end. Both providers offer nice bonus features, but only you know which one is right for you. Continue your search below to compare all internet providers available in your area!
