Ultra Mobile has introduced a number of changes to its prepaid offerings. Ultra Mobile adds new $39 plan and improves $34 plan by adding unlimited calling to Mexico mobile numbers. The carrier also discontinues $44 Data Plus plan with first 4GB of data at 4G LTE speeds and $59 plan with unlimited service, international features and first 2.5 GB at 4G LTE speeds. Ultra Mobile changes start being effective, January 21, 2016.

The new $39 plan includes unlimited domestic and international calling to 60 worldwide destinations, unlimited global texting, unlimited data with first 2GB at 4G LTE speed and a $2.50 Call Anywhere credit. Current $39 plan, however, offers unlimited talk and text domestic and international, domestic picture messaging and data with first 750 MB at 4G LTE speeds plus international features as $6.25 Call Anywhere Credit, 1000 Free INTL Minutes to over 15 countries plus unlimited international calling to 60 countries. Ultra Mobile customers who are enrolled to the old $39 plan prior to January 26, 2016, will be able to keep it.

The $34 plan has been changed too. First, the plan is not labeled as the Data Plus plan anymore. Also, the plan now includes unlimited calling to Mexico for both landline and mobile numbers. Previously, calling Mexico mobile numbers were charged 2.5 cents per minute. These charges have applied only to the $34 and the $44 Data Plus plans (the rest of the Ultra Plans included unlimited calling to Mexico mobiles) but now that $44 Data Plus plan is no longer available, all Ultra Mobile plans include unlimited calling to Mexico mobile phones in addition to landline numbers.

Remember, you must have an unlocked cellphone!

Before you can take advantage of Ultra Mobile’s Unlimited Talk and Global text, make sure you have an unlocked cellphone, so that it is free to accept any sim card from any service provider. If you want to break free from your current service provider Unlimited UNLOCK can unlock your phone in minutes, quickly, easily and cost effectively.

After these changes, Ultra Mobile plan offerings look like this:

• $19 plan – unlimited talk, unlimited text domestic and international, picture messaging limited to available data, 100 MB at 4G LTE speeds, $1.25 of Call Anywhere Credit and unlimited international calling to 11 countries (including unlimited calling to Mexico landlines and mobiles).
